RADIOTHERAPY SYSTEM PROVIDED WITH A PROGRAM FOR THE CALCULATION OF THE INTENSITY OF AN ELECTRONS BEAM

摘要

A system for radiotherapy is described. The system includes an accelerator of an electron beam, an imaging apparatus, a control unit and a radiation dose sensor connected to the control unit equipped with a program configured to execute the steps: (i) setting a first intensity of the electron beam, according to a predefined image of a target zone, the intensity to be emitted in a first radiation; (ii) operating said accelerator to emit the first radiation being a fraction of the first intensity; (iii) detecting a real intensity during the first radiation by the radiation dose sensor; (iv) acquiring an image of the zone; (v) calculating an intermediate intensity according to the image acquired in the step (iv) and according to the real intensity; and (vi) comparing the first intensity with the intermediate intensity to calculate a final beam intensity for a subsequent second radiation
