Around the middle of this video there’s a few good minutes of low small particle accelerators can be used to non invasively destroy brain tumours and other undesirable matter inside the body.
And the rest of the video is pretty interesting as well.
What happens if you put your head in a particle accelerator?

From web.
“Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator”.
(A side note from mollwollfumble, these high energy X-rays are not directly from the beam of the accelerator, because X-rays are uncharged and therefore can’t be accelerator. In a synchrotron (which this isn’t) electrons go through a set of magnets called wiggles, the resultant oscillating electric charge induces a perpendicular oscillating magnetic charge and together they generate electromagnetic radiation in the form of X-rays. The electrons are then bent out of the way and the X-rays continue straight ahead. The other way to generate X-rays is to have electrons impinging on a material that generates X-rays when hit by electrons, like the phosphor on a CRT TV screen generates light when hit by electrons.)
3-D conformal radiation therapy
3-D conformal radiation therapy is a common type of external beam radiation therapy. It uses images from CT, MRI, and PET scans to precisely plan the treatment area, a process called simulation. A computer program is used to analyze the images and to design radiation beams that conform to the shape of the tumour.
3-D conformal radiation conforms to the shape of the tumour by delivering beams from many directions. The precise shaping makes it possible to use higher doses of radiation to the tumour while sparing normal tissue.
Intensity-modulated radiation therapy (IMRT)
IMRT is a type of 3-D conformal radiation therapy.
Like 3-D conformal radiation, radiation beams are aimed at the tumour from several directions.
IMRT uses many more smaller beams than 3-D conformal and the strength of the beams in some areas can be changed to give higher doses to certain parts of the tumour.
Image-guided radiation therapy (IGRT)
Tomotherapy
Stereotactic radiosurgery
Radiation therapy can also be done using protons or electrons, but generally isn’t. Electrons don’t penetrate far into the skin.
Clinical trials are underway to compare radiation therapy using proton beams with that using photons beams. Some cancer centres are using proton beams in radiation therapy, but the high cost and size of the machines are limiting their use.
