Radiotherapy delivered on a linear accelerator (sometimes termed linac) is a form of ‘external beam' radiotherapy delivered using high energy X-Rays (photons). The department is equipped with 4 modern Varian TrueBeam linear accelerators, with ‘6 degree of freedom’ treatment couches all with advanced imaging packages, including respiratory and organ motion management systems. We also have access to the music library to have music you like playing in the treatment room while your undergo your radiotherapy.

The Radiotherapy service at UCLH also has dedicated CT, PET-CT and MRI scanners which are used to plan your radiotherapy treatment.

External beam radiotherapy delivered using a linear accelerator uses a dose of high energy X-Rays precisely targeted at a tumour or treatment target, whilst reducing the dose to surrounding healthy tissues and vital organs.

Treatment times will vary, depending on the area treated and your specific treatment position. A lot of the time will be spent putting you into the correct position. You will be asked to remove clothing that covers the area being treated, and then lie on a couch in the same position you were planned in. Using the marks made at your pre-treatment appointment, the radiographers will move the couch and the treatment machine into position.

 Each treatment lasts a few minutes and the Linear Accelerator (Linac) makes a buzzing noise when it is switched on. You will not see/feel anything during treatment.
