Pre-planning Linac Maintenance

Medical linear accelerators have continued to make progress through history since the late 1950’s and pave new ways for curing a variety of different cancers that once were not an option to treat. The design of the equipment combines the use of hardware and software that together gives the advantage of precision and overall success of today’s cancer treatment worldwide. Manufacturing and design continue to evolve and become a better tool for future use in reliability and efficiency but as with all mechanical systems, dysfunction and failures still exist. Having unplanned accelerator downtime and failures can impact a company and its patients very negatively. The scheduled treatments need to be performed at precise times given by the cancer specialists for an effective procedure while fighting against cancer. To avoid these situations from occurring, proper testing and maintenance of the radiology equipment must be done.

Steps During Maintenance

  1. Deliver a daily quality assurance (QA) treatment
  2. Automatically move and examine the log files that are created
  3. Create baselines, then perform daily operating and performance values to statistical process control (SPC) for examination
  4. Investigate if any alarms have been activated
  5. Inform the facility and system service engineers

Trained Professionals

Medical physicists will typically receive basic training of the principals of linear accelerators functionality, but much hands-on experience will be lacking since there is a limited access to linacs that’s are in clinical use but more importantly because these devices can only be adjusted with small set of parameters to maintain. For actual technicians, training for service personnel is generally one of the largest components to a person early on in employment. The process can be lengthy and costly and require unique training from the manufacturer of linear accelerator company.

Scheduled Maintenance and Repairs

Typically, Linac machines will be under an annual service contract that will provide scheduled, preventative maintenance throughout the year to keep the radiotherapy machines running optimally. Keep in mind, older equipment may reach their “end of life” period and may no longer be supported or even worse parts can become sparse or unavailable which may be a reason to start to look for replacement linear accelerators. Extending the life of your current systems with upgrades will be the most cost-effective option for your business. By repairing or upgrading the system this will also not only save money but save precious down time that will need to be taken if having to remove and install new equipment is needed. Not having a machine functioning will mean no treatments being performed which could cost you losing valuable patients.

Techniques Used in Radiation Therapy


The leading cause of death globally remains to be cancer. The word cancer is often used when a person describes how a loved family or friend dies. The first cancer treatments appreciated were introduced in 1895 after the discovery of Xrays. Cancer treatment has continued to progress at an increasing rate each year with new technology and growth in knowledge on the subject. There are many treatment options to be considered such as radiation therapy, surgery, chemotherapy, immunotherapy and hormonal therapy.

Radiation therapy continues to be one of the most important components of treatments available since it’s estimated 50% of all cancer patients receive radiation therapy during their sickness. The reason for such a high amount of uses for this type of treatment is the efficiency to target the cancer cells with beams of radiation produced by radiation equipment called a linear accelerator or LINAC. The high energy x ray beams destroy the cancer cells while preventing radiation damage from the healthy cells. Radiation therapy can be delivered in two different ways, the first is through External beam radiation. This type is the most common and is used from the outside of a patient’s body by aiming the radiation beams at the location of tumor. The second type of delivery is Internal radiation or also called brachytherapy. Internal radiation is done through the inside of the body by radioactive sources such as catheters or seeds directly into the tumor.

Fractionation

Radiation dose fractionation is radiotherapy delivered in a fractionated form. This type of therapy generally increases the survival of normal tissues and cells over the cancer cells. Normal cells multiply more slowly compared to the rapid increasing cancer cells which allows the healthy cells more time to heal before they replicate.

3D Conformal Radiotherapy

New technology has allowed older 2D radiation therapy that previously used rectangular fields based on plain X-ray imaging to be replaced with 3D radiation therapy based on CT imaging. This replacement allows for a more accurate target of the tumor as well as precise location of other normal organ structures for the most efficient beam placement and shielding to occur.

Intensity Modulated Radiation Therapy (IMRT)

Oncologists can create irregular-shaped radiation doses that take shape of the tumor while also having the ability to avoid other organs with IMRT technology. This process is all possible due to two factors which are inverse planning software and also computer controlled intensity modulation of multiple radiation beams during the process.

Image-guided Radiotherapy

The possibility to miss a tumor due to organ movement or the variations needed for each patient’s setup it becomes even more important for treatment options to be more precise than ever before. When critical tissue and organs are close to the tumor, a slight positional error could lead to radiation damage to the healthy cells. IRGT is created and utilized to allow detection of these such errors by the information taken through pre-radiotherapy imaging which can be used for corrections.

Stereotactic body radiation therapy (SBRT)

Another type of treatment that is possible today due to advances in newer technology is SBRT. This treatment delivers very high separate doses of radiation over only a few treatment fractions to destroy small tumors anywhere in the body of patient. The side effects of this however, tissues that are close in proximity to the tumor is likely to get damaged due to the high radiation dose. Since the amount of normal tissue effected is small in the high does region, toxicity is less.

Is It A Good Idea to Purchase A Pre-Owned Linear Accelerator?


Not every facility needs to purchase a new linear accelerator.  There are many times where a slightly used LINAC will serve the purpose of the facility at a fraction of the cost of a new one.  Some facilities however, benefit from the purchase of new equipment.  It really just depends on a number of variables to determine if a used, new, or refurbished linear accelerator is the solution for your facility.

When a facility needs the newest technology on the market, it is obvious a used or refurbished LINAC will not benefit them.  This is also the case if you are not looking to replace the machine anytime soon.  A brand new or almost new linear accelerator is a better option for facilities that don’t want to replace their machine in the next ten to fifteen years and are looking for the latest and greatest technology. 

The struggle between buying new, refurbished, and used radiation oncology equipment is a struggle many facilities face.  It is probably important to note however, that the minute you use a new linear accelerator it becomes used.  So not every used machine is “used” to the same extent.  Used and refurbished linear accelerators can be suitable for facilities under certain circumstances including:

  • When your facility is treating less than 8 to 10 patients a day, the revenue you are producing will not sustain the expense of a new machine.
  • Areas where reimbursement is low, and your clinic needs to be profitable to continue providing treatment may be better suited to purchase a used or refurbished unit.
  • The machine will be used in a limited capacity and doesn’t necessarily benefit from the latest technologies.  These circumstances may include using the machine for research, treating animals, or non-medical, industrial purposes.
  • Your facility will be able to afford the latest and greatest in the next couple of years but just can’t without first building a profitable practice.
  • You are opening a new medical center and don’t have the resources to secure financing on a new machine. 
  • You are moving to a new location, can’t afford downtime, and need to be able to treat patients during the process and currently only have one machine.
  • If your facility needs a back up to prevent downtime in patient care during maintenance and repairs on your main LINAC.
  • A new facility is being built but you need a temporary way to treat patients.
  • When the hardware aspect of treatment is not as important as the software.  Used and refurbished equipment can have updated software installed when your budget doesn’t allow for both upgraded software and hardware.

Obviously, brand new, state of the art equipment when purchasing linear accelerators and CT scanners is something all facilities desire, it is not always the most practical situation.  Purchasing used equipment doesn’t mean that your facility is operating with technology that is necessarily out of date.  Often newer style equipment can be acquired with little use.  It is important to remember just because it is used it doesn’t mean it is used up.  Used simply means that at one time or another it has been in use for patient care.  It could be the latest Varian model used for treatment in a facility briefly.  Used equipment can often save facilities a great deal of money in machine costs and financing.

A Little Preparation Goes A Long Way In Maintaining Linear Accelerators

Linear accelerators, LINAC, are large scaled medical devices that deliver external radiation in the form of a beam to cancerous tumors in order to shrink them.  As with most medical equipment, LINAC systems are expensive which is a barrier that many facilities face when purchasing a new or refurbished unit. 

With the expense of these large scaled systems it is important to make sure they are properly maintained and that you have access to linear accelerator parts for repair as needed.  Medical facilities can contract with companies that specialize in maintenance and repair services of LINAC systems such as Acceletronics or have on staff a team of professionals whose job it is to provide these services for their equipment.  There are advantages and disadvantage to both options, facilities choose based on their budget and facility needs.

Linear accelerators have evolved over the years. LINAC machines no longer only provide external radiation beams for treatment.  Major advancement in this technology include onboard imaging systems and portal dosimetry. Such complex systems require biomedical and clinical engineers to not only understand what these machines do but also how they are operated.  Even with advanced training, until the engineer has hands on experience it is difficult to truly understand how the machine functions. 

Not only is the linear accelerator expensive but the expertise to use and understand the machine is costly as well.  This again is an issue that faces many medical facilities.  These two factors alone make up the most significant aspect of expense faced by facilities when deciding on the purchase of equipment. 

All linear accelerators are not created equally and therefore when replacing an existing system there will be a significant cost to not only bring new equipment in but also the training on the individual piece of equipment.  One way to combat this is to replace existing LINAC with identical refurbished linear accelerators

We have discussed a lot about the expense of these units however there is also significant revenue to be gained by having external radiation treatment available to patients seeking treatment for cancerous tumors.  It is important for facilities to make sure these machines are functioning at peak capabilities at all times.  Downtime not only impacts revenue but also patient care.  In order for patients to have effective treatment for their tumors it is important they are able to strictly follow the treatment schedule laid out by their radiation team.  If equipment is down this is not possible.

To ensure that patient care and revenue is not affected by machine downtime it is crucial to maintain equipment.  Machine maintenance includes repairs in anticipation of failure.  If a parts failure is eminent based on previous experience it behooves the facility to purchase the LINAC replacement part ahead of time so that service can be provided around patient’s treatment schedules.  This allows facilities to schedule downtime to prevent unplanned downtime.

FAQs On Selling and Servicing New and Refurbished Linear Accelerators and Parts


The biggest factors that haunt healthcare facilities and providers in today’s environment center around the expense and quality of varying capital investments.  How can facilities run at peak capacity, preserving patient care, and providing positive outcomes with the unavoidable expenditure involved in the service and maintenance of medical equipment

In order to maintain their cutting-edge facilities, healthcare providers must ensure their medical equipment is reliable, sustainable, and can produce the best patient outcomes today and in the future.  In order to provide patients top notch medical equipment without repair or maintenance delays facilities often enter into service contracts with either OEM, manufacturer provided, or third-party service provides. Often many OEM and manufacturer provided medical equipment service providers quickly try to claim that only they are able to provide proper post warranty services often bundling products, services, maintenance, and upgrades in packages to hold facilities hostage in using their service. 

What can healthcare facilities and providers do to combat the monopoly OEM and manufacturer provides service companies seem to dictate within the industry?  There are alternatives to these medical service providers known as third-party medical equipment service companies. Companies such as Acceletronics and Radparts are medical equipment service and part providers that guarantee the best value and service for equipment and facilities.  This is done through careful consideration of what medical facilities are considering when choosing a service provider. 

Careful consideration has been given in our service model to not only our reputation within the industry but our response time, access to parts, and performance.  Your service contract with a third-party medical equipment service provider is only one aspect of what you are purchasing, uptime, and performance are the others.  Your equipment is used to deliver patient care.  What you need is a guarantee that the medical service, maintenance, and repair provider of your facilities linear accelerators and CT scanners is in the best condition possible and that you are receiving the best value possible. 

Before you purchase any service contract for medical equipment it is important to consider what is most important.  When creating a model for equipment service, repair, maintenance, and part sales the professionals at Acceletronics and Radparts have considered various industry quality standards, short- and long-term sustainability, and the total cost of equipment ownership. 

Quality Standards – Superior patient outcomes rest on the quality of service.  One-way quality is measured is by using a standard put in place through the International Organization for Standardizations.  The ISO 9001 Quality Certification was developed to assist customers in making informed decisions when quality is vital.  The ISO 13485 is another quality certification however it is applicable exclusively to the medical device industry. 

Sustainability – Up to date information and new technology sustains your equipment thus service providers must be able to provide service personnel with on-going, proper training.  Before signing a contract with a service provider ask about training programs personnel are required to participate in.  It is important quality training occurs regularly to meet or exceed OEM standards to provide valuable services without downtime.

Total Cost of Ownership – Radiation departments experience great pressures to reduce expenses. Not only do facilities need to concern themselves with the purchase price but also maintenance expenses, and software upgrades.  Often facilities think bundling these services is the most appropriate choice however, this may not always be the best choice when negotiating.  It is important to pay only for those services that you will use.

Choosing To Replace Medical Equipment Opposed to Repair


There is quite a balancing act that goes on within healthcare facilities when it comes to whether or not medical equipment should be repaired or replaced. Unfortunately there is not one answer to address the issue.  Decisions for repairing or replacing medical equipment such as linear accelerators and CT scanners needs to be done on a case by case basis.  The most important factors being how the decision affects patient care and patient outcomes.

Many professionals involved in the decision to replace or repair medical equipment find weighing the costs and patient interests to be a difficult task.  Facility decision makers need to determine the risks vs the rewards in how long to keep large scaled medical equipment in action.  Preventative and corrective maintenance must be evaluated on a per machine basis to ensure the best decisions are made. 

It is impractical to repair medical equipment when:

Replacement Parts Are Scarce: Replacement parts for LINACS or CT scanners aren’t common off the shelf items that you can find at any medical supply store.  In fact, with manufacturers in a race to keep up with the latest and greatest technologies in equipment they are constantly phasing out older equipment which makes finding parts to repair medical equipment harder and harder to find. This alone makes it scary to rely on older equipment for critical patient care.

The Cost of Service: If medical equipment is not maintained or repaired by in house technicians’ facilities must look at the expense of service plans.  Another factor is that as equipment ages, replacement parts are harder to find if not obsolete.

Patient Care Will Be Disrupted:  When large scaled equipment starts to break down on a regular basis and interrupts patient care this wreaks havoc with patient care.  If this is on-going, it can greatly affect your service and dissatisfied patients will seek care elsewhere.

On-Going Equipment Failure: Sometimes the equipment that you have is a giant lemon.  If it is found that your device is failing time and time again it may make sense to replace it.  Sometimes there is more liability in keeping a piece of equipment around that continues to fail than starting over.

There is a lot that goes into replacing a large scaled piece of medical equipment like a LINAC system, so it is crucial to have a plan in place for when the need arises.  Not only does new equipment need to be purchased, the old equipment needs to be moved out to make room for the new.   It is important to evaluate and reevaluate equipment frequently in order to avoid costly surprises.  This is especially true in smaller facilities with stricter budgets.

Purchasing vs. Repairing Medical Equipment


Many medical facilities and healthcare clinics find themselves mauling over questions regarding repairing or replacing medical equipment. Questions may include ones such as the following:

  • What is the typical lifespan of the equipment?
  • Are we near the end or at the beginning of the equipment’s lifecycle?
  • Is it going to be cheaper to replace the piece now or to repair it?
  • Are repairs feasible and if so, are they cost effective?
  • When repaired will the equipment still be able to provide the high patient care standards we desire?
  • What is the cost of removing the old equipment?
  • Do we see maintenance costs of the older equipment increasing?

Often the choice to purchase a new piece of equipment verse repairing an older piece of equipment has to do with the cost of maintaining the older unit.  Medical facilities and clinics figure if they are spending a couple of thousand dollars to maintain it then it is most likely better to replace it with a new piece.  When it gets too expensive to maintain it is time to purchase a new piece of equipment

For larger pieces of equipment like linear accelerators, CT scanners, and other radiation therapy equipment parts may start to become obsolete.  When this occurs, parts for older equipment LINAC become quite scarce.  It is important for facilities to ensure there are enough replacement parts available to maintain their equipment because the parts won’t be available any longer. It doesn’t mean that facilities need to plan for new equipment in the next year but that they should start planning for alternative part sources and planning for new equipment.

Make sure you are totaling up the annual costs of medical equipment repairs. Costs for parts and repairs can change as parts become scarce.  Obviously, manufacturers of large scaled equipment want you to buy new sooner rather than later while the finance people within your facility want you to maintain the equipment as long as possible, especially when technology has not changed a great deal.  Obviously, the goal is to make sure you are not spending valuable resources unnecessarily. 

Medical facilities should find various resources in which to seek opinions on equipment and whether it should be replaced or not.  Finding a solid medical repair and maintenance partner, such as Acceletronics and Radparts when determining whether to replace or repair an item, as well as what to do with older pieces when purchasing new ones.

The Ins and Outs Of Radiation Therapy Using a Linear Accelerator


A linear accelerator is a large scaled piece of medical equipment that is used to treat cancerous tumors.  It does this through a process of high energy x-rays that conform to the shape of a tumor and emits a radiation beam that destroys cancer cells while trying to spare the surrounding healthy tissue.  Linear accelerators have a number of features that are built in which works to ensure the patients safety.  These measures prevent dosages higher than what the patient has been prescribed to be given. 

When you are schedule to receive radiation therapy using a linear accelerator, your oncologist will deliver the treatment that was planned between them, the dosimetrist and your physicist.   The oncologist will double-check your treatment plan each and every time before they begin treatment.   This ensures quality control and ensures that your treatment is delivered exactly as it should be. 

Linear accelerators delivers external radiation therapy for patients with cancer. The LINAC is used to delivery treatment on a variety of areas throughout the body.  High energy x-rays are delivered directly to the tumor using a radiation beam that is delivered from the linear accelerator.  The treatment is designed to shrink and destroy the cancerous tumor without harming the healthy tissue that surrounds the tumor.  LINAC is used to treat cancerous areas throughout the body using all of the conventional radiation techniques including: IMRT, IGRT, VMAR, SRS, and SBRT. 

Linear accelerators work using technology similar to a radar.  In the “wave guide” a part of the accelerator, electrons collide with a metal target to produce high-energy x-rays.  The high-energy x-rays exit the machine in the shape of a patient’s tumor.  These beams are shaped by a multileaf collimator that is within the head of the linear accelerator. 

Patients are put onto a moveable treatment couch that is positioned properly and are asked to lie still.  It is important to note that the treatment couch can move up, down, right, left, in, and out.  The radiation beam comes out of the gantry, part of the accelerator, that can be rotated around the patient.  These two systems, working together, can deliver radiation in a variety of angles.

Linear accelerators are operated by a radiation therapist.  There are a team of experts who work together to create a treatment plan.  A radiation oncologist, a medical physicist, and a dosimetrist work in conjunction of one another to come up with a treatment plan.  The radiation oncologists prescribes the correct treatment volume and dose.  A medical physicist and dosimetrist determine how your prescribed dose is delivered and calculated.  

Patient safety is insured in a number of ways.  Before treatment is given the plan is developed and approved in collaboration with your team. This plan is continually reviewed for quality assurance.  Safety measurements are built directly into the accelerator that does not allow a higher dose of radiation to be delivered to patients.  Before a patient is treated the radiation, therapist will perform unilateral checks across the LINAC.  More thorough linear accelerator checks are done monthly and annually.  Specialized companies are available for hire that maintain, service, and repair linear accelerators.  It is important to have access to LINAC service providers and LINAC parts for repair.  The less downtime a facility incurs the higher the quality of patient care they can provide.

Patients are supervised throughout treatment using monitors and microphones that in the room.  This allows the patient and radiation therapist to communicate.  The position of the radiation beam are continually checked to ensure the positioning has not moved from the original treatment plan. 

The safety of the staff and patient are crucial when using linear accelerators in treating cancerous tumors.  The LINAC is installed in a room all by itself.  The walls of the room are made from lead and concrete to eliminate the high energy x-rays from escaping and exposing people outside of the room.  Radiation therapists do not tun on the LINAC until they are safely outside of the treatment area.  Linear accelerators will only emit radiation when the machine is in use.

Answers to The Top 4 Questions About Radiation Therapy

Anyone that is starting a new medical treatment has a right to be a little nervous.  This article is being written to help ease the anxiety of cancer patients that are scheduled for radiation therapy.  Fear comes because of the unknown and common misunderstandings patients have about radiation. 

Radiation therapy is delivered using a large piece of medical equipment known as a linear accelerator.  With maintenance, repairs, and part replacement linear accelerators can deliver radiation to an average number of patients for between five and ten years.  Below we will answer the most commonly asked questions about radiation therapy using a linear accelerator, LINAC.

Is Radiation Therapy Painful?

Thankfully radiation therapy is not painful.  Patients often report that they do not experience any sensation when the radiation is delivered from the LINAC.   A few patients have reported that they feel a slight warm tingle in the area where the LINAC is delivering radiation.  The skin in the area where linear accelerators deliver treatment can become dry and itchy over time.  This can cause some discomfort but definitely not enough to stop treatment.  Skin reactions due to radiation can be treated with over the counter ointment. 

Does Radiation Therapy Cause Me to Be Radioactive?

Radiation therapy only makes patients radioactive when internal radiation is given.  Patients are radioactive while the radioactive materials are in them.  These patients are secluded in a private hospital room.  Patients that are treated using a LINAC through external radiation, will not be radioactive at all.  External radiation delivers a precise dose of radiation to the cancerous tissues instantaneously.  With external radiation the radiation does not linger. Once the LINAC is turned off the radiation isn’t an issue.  In external radiation, patients can continue on their normal routines without worry. 

Will I Lose My Hair During Radiation Therapy?

Radiation is considered a localized treatment which means that it focuses directly on the area being treated.  This being said you can expect hair loss in the area of treatment however unless treatment is done on your head you shouldn’t experience hair loss.  Confusion occurs because people associate radiation and chemotherapy as one in the same therapies.  The difference is that chemotherapy is a systemic treatment which means it affects the entire body.  During chemotherapy there is a likelihood that patients will lose their hair.

Should I Expect to Experience Nausea and Vomiting? 

Radiation therapy doesn’t usually cause patients to feel sick.  If treatment is given in areas such as the liver, brain, or gastrointestinal tract patients have more of a risk to experience nausea.  Also, patients that are going through chemotherapy and radiation at the same time there is more of a risk for feeling ill.
