摘要：
A radiation dose control device for controlling an electron beam pulse delivered during a therapy session of IORT (Intra-Operative Radiation Therapy), comprising a PWM system configured to provide an electron injection at a DC voltage at each pulse of an input electron beam (FE) sent to the input of an electronic gun (G) of a linear accelerator or linac (AL), so that the output electron beam (FU) exiting said linac (AL) is highly stable, and so that a variation of the radiation dose of said output electron beam (FU) results only from the variation of the delivery time of said input electron beam (FE) said dose variation of the output electron beam (FU) is thus directly proportional to said delivery time of the input electron beam (FE).
