Key Points to Consider for Linac Removal

Removing a 25,000 lb piece of machinery from a medical clinic or hospital, what could go wrong? It can be crucial to other surrounding equipment and to your facility to have safe and efficient removal services performed so that your facility will have peace of mind knowing that this process will be handled correctly. A few tips below will help this removal process go more smoothly and will get you to the goal of out with the out and in with the new more quickly.

Removal Path

To start, cleaning of any removable clutter is always overlooked and can become an obstacle that can be avoided. Measuring will be the next step to take when its time to start moving any type of equipment. A tape measurer will be your best friend since when it comes to moving high or low energy linacs, each have a minimum requirement for the number of inches required for room clearance.  Accurately measuring all building doors including the vault and outside door along the removal path is very important. Prior to the arrival or replacement equipment, a professional vendor will request a rig info sheet to be submitted to guarantee that there is no door frames or walls that will need to be removed. If the vendor does not ask about the measurements beforehand, this is a red flag that you should be looking for equipment elsewhere.

Safety Concerns

When transporting heavy equipment at any times, the safety of the removal team is of utmost importance. If the above-mentioned measurements are done inaccurately and realize that a vault door must be removed with late notice, this will pose a very big safety hazard. Depending on size, vault doors can easily weigh a few thousand pounds and unfortunate deaths have resulted when removal of these doors have been done incorrectly. When they doors need to be removed, it is critical that they are removed by professionals that have experience in the field.  Last minute decisions for vault door removal will also cut into extra expenses that was not part of the company budget so it again if very important for the measurements to be calculated right the first time. Proper liability insurance should be provided by your vendor when on site during the removal process as well.

Loading Space

Once you have the old equipment outside the next step is often overlooked as well. The loading area needs to have enough space in order to load the linear accelerator into trailer for transportation. Facilities will typically need to block off any side streets or parking spots to allow a safe loading area. If loading space is unavailable, the removal team will need to utilize a forklift of suitable size to lift and move machinery to the trailer manually.

Facility Jobs

No matter the size or details of removal that is performed, there will be responsibilities of the facility that will be requested. Generally, the removal team will ask local facility engineers, electricians, or plumbers to turn off the water or other power sources that are attached to the specific equipment that is being removed. This will protect the office building from having potentially dangerous live power to the area and helps to not disrupt any of the surrounding rooms that lighting and power may be connected to as well. Many times, the facility will manage and schedule the removal times so that it is occurring after hours or assist in security throughout the building.

Improving LINAC Service Response Time


Linear accelerators and complex support devices are at the heart of today’s radiation oncology.  As technology continues to advance and change the way in which LINAC systems treat cancerous tumors, it becomes increasingly difficult to manage the way in which equipment maintenance, malfunction, and breakdowns are managed.  The strategies to manage quality, mitigate risk and analyze failures have improved to adjust to the changing needs of radiation oncology equipment. 

Manufacturers of oncology equipment add guidelines to ensure successful management of equipment maintenance including system monitoring and cyclical measurements of key functions verse pre-specified tolerances.  This information was previously documented by hand whereas in today’s environment data can be recorded, distributed company-wide, and stored electronically. IT plays an integral role in storing and managing the data which can then be integrated into the everyday workflow in the radiation oncology department.    

Work to cultivate IT clinical management solutions in the radiation department is often done in house working in collaboration with equipment vendors.  This process is an essential component in quality management of radiation oncology equipment services

Service and support of linear accelerators are a key element in quality management in the radiation oncology department.  In most facilities, radiation therapists will report all technical problems with the LINAC to a clinical medical physicist who then reports the events of the machine’s failure to the vendor’s dispatch center to schedule support.  When this call is made the therapist or physicist reporting the LINAC failure will provide the identification of the linear accelerator, the location of the machine, and a detailed report of the problem including what issues led up to the failure..

Depending on where the machine is located, the vendors dispatch center will provide information to equipment engineers at their technical support help desk.  Together the user and engineers will attempt to diagnosis the issue at hand and coordinate actions for repair. 

Facilities looking to improve the efficiency of support and service to linear accelerators when failure occurs can implement key changes in the overall process.  These procedure modifications include:

  • Lessen the number of steps involved in reporting the LINAC failure to the vendor’s support team.
  • Reduce duplication and surplus in the diffusion of information related to the linear accelerators’ failure.
  • Record events electronically for improvement and evaluation of delivering services related to LINAC maintenance and repairs.
  • Utilize remote support from vendor approved engineers that are familiar with the installed system and its maintenance and service history.

3 Tips For Installing or Replacing a Linear Accelerator

New linear accelerators can cost a medical facility between 1 and 5 million dollars.  The expense of owning a LINAC does not stop once it has ben purchased.  There are items outside of the actual equipment purchase such as a simulator, training computers, treatment rooms, salaries, ongoing training, operation expenses, maintenance, repairs, and more.  The total cost of large scaled medical equipment is never one that should be underestimated.  Whether you are installing a brand new or refurbished linear accelerator, installing a LINAC for the first time, or replacing an existing one there are three tips the professionals at Acceletronics want to give you.

Step One – Plan, Plan, and Plan Some More

The installation planning process for a linear accelerator takes between six months to eight years.  The length of time for planning your project can span almost any length of time.

  • When planning new technology, you will first want to establish the technology that you need in order to treat patients.  What types of cases will you be treating?  Consider the options IMRT, IGRT, and so on.
  • If you are installing a linear accelerator in new construction, you will want to consider the constraints that come along with that.  What local permits do you need, do you have the proper power supply needed for this large scaled equipment, are there constraints that will limit your installation?  If you are renovating a space consider the rooms constraints, size, location of isocenter and so forth.
  • Create a timeline for major milestones.  When will the vault be completed, when are vendors scheduled to install computers?  When planning these things consider potential areas where conflict can occur and come up with a backup plan.
  • Once the goals are established, a budget is needed to acquire the new equipment.  Consider other aspects as well such as training, equipment needed to run the LINAC and treat patients, and the extra items that can be forgotten about when focusing on the large scaled purchase.

Step Two – Hire Based on Experience

When hiring a team of professionals, it is crucial that you hire experts.  Experts are needed for designing the vault, construction, providers of equipment and supplies, IT support, clinical implementation teams, and such.  Don’t trade cost for quality.  Sometimes a little bit more money now can save you a great deal of money later on down the road.  Ask for references when working with different vendors.  Hire only those vendors that understand the collaboration effort needed to install medical equipment such as CT Scanners and Linear Accelerators. 

Step Three – Commit to Quality

When buying a used or refurbished linear accelerator there is a three-step process that you should follow to ensure you get a machine that meets your needs and beyond.  These steps include: a review of the LINAC’s service history (look at major service events such as waveguide replacement), review the machine’s utilization and beam hours, and perform a physical inspection of the machine.

Reasons To Look Into Purchasing Refurbished vs. New


There are many reasons that health care facilities look into purchasing refurbished linear accelerators verse new.  Most assume that refurbished medical equipment is purchased solely because it is more affordable than new however that is not the only reason to consider. 

Look into refurbished LINAC systems when:

  • Treating fewer than ten patients a day

When medical facilities are not exclusively treating patients seeking radiation using a linear accelerator there may not be the funds to support the expense.  Health care centers that treat less than ten patients a day using a LINAC benefit from purchasing a refurbished system.  A previously owned, refurbished linear accelerator is less expensive and thus the monthly expense to lease/finance is lower.  What this means for your facility is that the payment is able to be covered by the few patients being treated daily.

  • You live in a location where reimbursement rates are low

When a medical facility is located in an area where facilities need to be profitable to continue running and compensation rates are low it is important to keep expenses low.  Public clinics don’t need to worry about being lucrative however that is not the same for all health care facilities. 

  • There is not a need for the latest technologies

When a medical facility is using a LINAC system and only requires partial use of its technologies then a refurbished linear accelerator is a perfect choice.  Many veterinarians choose to purchase refurbished linear accelerators to treat pets and animals.  They don’t require all the bells and whistles found in new radiation so refurbished equipment makes sense. 

  • You are just starting out

When a medical facility is just opening, they may not have the revenue base to purchase more expensive medical equipment with the newest technologies.  Healthcare facilities that are looking to upgrade to new technology in four to seven years but need to treat patients and generate funds benefit from purchasing refurbished medical equipment.  Health care centers often want to buy brand new equipment when starting out, but it is a huge risk to invest capital that is not guaranteed in such expenses.  Pre-owned, refurbished LINAC help to mitigate the risks while allowing facilities to effectively treat patients.

  • The facility needs to move locations

When a medical facility has one linear accelerator but intends to move locations and are unable to have down-time the purchase of a refurbished machine is a good idea. Linear accelerator relocation can take upwards of four weeks so many facilities choose to purchase an identical machine to install at the new center.  When the move has been completed the equipment can be sold or kept as a backup.

  • A backup machine is desired

When a medical facility wants to ensure they are always able to treat their patients a back up linear accelerator is necessary.  This is often the case when a facility has a large patient load.  When the main LINAC is down for maintenance or repair patients can still be treated using a back up machine.  Refurbished linear accelerators are a great backup solution.

Buying used and refurbished linear accelerators can save medical facilities a great deal of money.  This is fairly critical when it comes to the limited budgets that growing healthcare centers face.  The question most often asked is about the HV (high voltage) hours, beam hours, and how important their role is in determining the wear and tear of a LINAC

The most universal analogy comes down to the mileage of a used vehicle, the more miles usually means more wear and tear.  The higher the mileage, the less you should expect the resale value to be.  Beam hours are very similar.  Beam hours are equivalent to the time that the beam has been in use.  Thus, higher HV hours often means that these machines will be priced lower than LINACS with lower beam hours.  This of course assumes all other things are equal.

In reality a dozen factors go into determining the price facilities will pay when purchasing a used linear accelerator.  These include factors such as manufacturer, age of LINAC, updates to software/technology, and upgrades to the machine.  The chart below offers a reasonable explanation to what facilities should expect in regard to beam hours.

Expected Time Until Machine Replacement/Major Refurbishment
5 years 10 years 15 years
Patients Seen Per Day 10+ 2000 Beam Hours 1500 Beam Hours 1000 Beam Hours
<10 3000 Beam Hours 2500 Beam Hours 2000 Beam Hours

On the top you will see a number that reflects the years a used machine is expected to be in place at the new facility.  When a facility is getting started, doesn’t expect to see a lot of patients, and expects to have a higher revenue to purchase equipment in the next couple of years a used LINAC with higher beam hours is acceptable to be purchased.   However, if this same facility hopes to hold onto the machine for an extended period of time or expects to see a high number of patients, they should re-evaluate the number of acceptable beam hours that can be on a used LINAC. 

Situation: A health care center looking into adding a cancer treatment center to an already booming facility.  They are expecting that as they make available this new treatment option that their revenue will increase.  They also expect that as patients become aware of the option for treatment the number of patients, they can expect to see should be higher than they are to begin with.  They want to purchase a LINAC without having to replace it for about 10 years.  What amount of beam hours should they be looking for on a used LINAC? 

This facility, because they are assuming, they will see a high number of patients for treatment as the word spreads that they are offering LINAC treatment should assume that in time they will be seeing more than 10 patients a day.  Even if they start out slow at 5 patients a day now, it is assumed that they will be treating upwards of 15 or more eventually which will average out.  Because they want the equipment to last at least 10 years this facility should only be looking at LINAC systems with between 1000-1500 used beam hours anything with more than that will not serve the purpose for the volume of patients they are expecting or the years that they wish to use this piece of medical equipment.

Another thing a facility needs to consider is how often IMRT and VMAT treatment will be used.  These two types of treatment options consumer more beam hours.   This should be considered when looking into a used LINAC.   

This illustration should be used only as a guideline.   With proper, regular maintenance, servicing, and parts replacement, used/pre-owned linear accelerators can last for years even with a high number of beam hours.
