Linear Accelerator (LINAC)

Bangkok

Linear Accelerator (LINAC) in Bangkok is available at 2 hospitals in the Voumed network.

A linear accelerator, usually called a LINAC, is the machine that delivers most external beam radiotherapy. It accelerates electrons to produce high-energy X-ray or electron beams, then shapes and aims those beams at a tumour from many angles, so the planned dose reaches the target while nearby healthy tissue receives as little as possible. It is used for many common cancers, either to cure, to control the disease or to relieve symptoms. International patients usually look for a centre that combines image-guided delivery with an experienced planning team, and shorter courses can make treatment away from home more practical.
