What should you know about Varian TrueBeam linear accelerator?
Short answer
A Varian TrueBeam linear accelerator is a radiotherapy machine that delivers carefully planned beams of radiation to a treatment area while the treatment team positions and monitors you.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

What the machine does
A linear accelerator creates high-energy radiation for cancer treatment. TrueBeam is a platform designed to deliver treatment from different directions as the machine moves around the treatment couch. Planning software helps the team shape and aim the dose toward the intended area, with the goal of limiting exposure to nearby healthy tissue. The exact technique depends on the cancer type, its location, the treatment plan, and your overall care goals.
Before treatment, you may have imaging and a simulation appointment so the team can map your position and treatment area. During a session, you lie still while the machine moves around you. The machine does not touch you, and the radiation itself cannot be seen or felt. The team can hear and speak with you during treatment, and the session length varies by plan.
How to prepare
Follow the instructions from your radiation oncology team about eating, drinking, medicines, skin products, and arriving with any positioning aids. Wear comfortable clothing that allows access to the treatment area. Tell the team about pregnancy or a possible pregnancy, implanted devices, difficulty lying flat, pain, or anxiety before the planning visit. Keep appointments for review because the team may adjust care based on your examination and symptoms.
When to contact your care team
Contact your treatment team promptly if you develop new or worsening pain, skin changes in the treatment area, marked tiredness, trouble swallowing, breathing symptoms, persistent vomiting, or difficulty keeping fluids down. The relevant warning signs depend on the body area being treated. Seek urgent medical help for severe breathing difficulty, chest pain, confusion, fainting, or sudden weakness.
Questions for your doctor
Ask which radiation technique is planned, why it suits your treatment area, how you will be positioned, whether an immobilisation device is needed, what side effects may affect your daily activities, and who to call between appointments. You can also ask how treatment fits with surgery, medicines, or other oncology care.
Questions people ask
Can you feel the radiation from a TrueBeam machine?
Radiation is not visible and is not felt as it is delivered. You may hear the machine moving, while the team watches and communicates with you.
Is TrueBeam suitable for every cancer treatment?
No single machine or technique suits every person. Your oncology team chooses equipment and beam delivery based on the tumour location, treatment aim, imaging, and your health.
What should I do if I feel unwell during a session?
Tell the treatment team immediately. They can pause, check how you are, and decide what support or next step is needed.
