[News in radiotherapy of solid tumors]

New in radiotherapy of solid tumors. The new irradiation techniques integrate the latest technological developments in medical imaging and computer science, dosimetry, and linacs into the treatment procedure. They raise new hopes for the treatment of solid tumor pathologies. Three techniques seem particularly promising: intensity modulated radiotherapy, respiratory gating radiotherapy, and stereotactic radiotherapy. The emergence of artificial intelligence, and particularly its applications in the field of imaging, opens up a new field of research. The purpose of these different innovations is to achieve very high precision radiotherapy, which makes it possible to better adapt the radiation fields to the tumor and thus protect the critical organs.
