3D conformational radiotherapy

Oncologist

The most widely used external radiotherapy technique today is 3D conformational radiotherapy (three dimensions). This technique makes it possible to match as precisely as possible (to conform) the volume on which the rays will be directed, to the volume of the tumor. It uses 3D images of the tumor and neighboring organs obtained by CT scan, sometimes combined with other imaging tests (MRI, PET, etc.). Conformational radiotherapy is used for the curative treatment of tumors of the prostate, thorax, abdomen, pelvis, and increasingly for ENT and brain cancers.
