Should You Repair It or Replace It: LINAC Systems

LINAC, linear accelerators, are an essential part of treating tumors and destroying cancer cells in people, while leaving the normal tissue alone. While this is an effective treatment for specific types of cancers, as the machines have built-in safety measures that only deliver the required dosage, they can also start to fail over time. When the system fails you will question whether you should continue to repair it or if it is time to replace it.

The Importance Of Regular Maintenance

It’s up to the medical physicist to ensure that their clinic or hospital’s LINAC system is functioning properly. If there is any doubt, repairing or replacing medical equipment may be required.  It’s important that all patients who’ve been scheduled for radiation therapy are assured of safe and accurate treatment. They need to also be assured of timely treatment, with few delays. Treatment is more specialized and intricate with linear accelerators. It’s very important to keep to regular servicing LINAC systems.


Servicing linear accelerators is a specialty that is best left to the professionals. There are many safety checks in place. The LINAC itself may present warnings that it’s due for servicing LINAC systems.  When warnings are present it is important to see what needs to be repaired and to see if repairing it or replacing it with a refurbished linear accelerator is the best choice.

Keeping Machine Functionality Effective

There are a wide range of professionals who use this equipment to help patients. The medical physicist and the dosimetrist will determine the exact prescribed dosage, and calculate the right amount of time for that dosage. The oncologist will be prescribing the volume and dosage. It’s important to have a functioning system so that there are not additional problems and that the patient receives effective treatment. Linear accelerator maintenance is also a part of the process to keep your LINAC systems working well. If the technician finds something wrong with the system, they will advise of fixing it or replacement.


Patient safety is also of paramount important. The radiation treatment plan is double-checked, with several steps and quality-assured procedures so that the treatment is delivered exactly. Following all these steps, the machine should not deliver a higher dosage than prescribed.


Today’s modern linear accelerators also have an internal checking system that keeps the machine from being turned on unless all the prescribed requirements have been fulfilled. If for some reason you are initiating treatment with the patient, but the machine refusing to turn on, it’s may be time for servicing LINAC systems or replacement.

Ensuring Specific Parts Like Beam Position

During treatment, the radiation therapist will be continuing to observe the patient with a closed-circuit television monitor. There is also a microphone in the treatment room so the patient can speak to the radiation therapist if required. Just some of the items that are checked during this process include the port films or x-ray that are taken with the treatment beam, and the cone beam CT. This ensures that the beam position doesn’t change from the original plan. It’s important for servicing linear accelerators to ensure that these safeties stay in place. If they fail, it could be time for a replacement.
