SRS (Stereotactic Radiosurgery)

irradiation to brain lesions in very few sessions, preserving as much as possible the structure and function of the surrounding normal cells. This technique delivers a fractionated dose that is incapable of causing damage to healthy tissues but accumulates in pathological tissues, thus avoiding the occurrence of sequelae or complications. This method is essentially used when the lesion is very close to particularly critical structures, such as the brainstem, optic nerves, chiasm, or pituitary gland.

Each treatment session is administered with the IMRT technique, during which not only the shape of the irradiation field conforms to the shape of the tumor with sub-millimeter precision, but the intensity of the radiation beam in each field also varies, adapting to the anatomical characteristics of the tumor and normal structures.
