Recommendations for treatment with IMRT for prostate and head-neck cancer. Axencia de Avaliación de Tecnoloxías Sanitarias de Galicia.

Intensity-modulated radiation therapy (IMRT) is an advanced form of radiotherapy for the treatment of cancer that allows, on one hand, to administer a more homogeneous dose to the patients on the volume to irradiate (which would increase the local control of the disease), and on the other hand, to diminish the toxicity in the organs at risk. This type of treatment is based on imaging techniques, on computer dosimetry programs, and on more precise immobilization accessories. Before delivering IMRT it is necessary to establish a protocol that includes the different phases of the treatment process, that is, the obtaining of anatomical data, beam definition, calculation, dose distribution, and treatment performance and control.
