Abstract: The present invention concerns a device for controlling the radiotherapy treatment of cancer patients, comprising a gas chamber (10) with flat and parallel electrodes (7), placed at a certain distance (d), a window (2) placed above an electrode (7) and insulating means (4, 5, 6) placed below the electrode (7). The chamber (10) is connected to a collector (8) through which a noble gas is introduced into a cavity (11) of the chamber (10), so that the electric field inside the chamber (10) is due to the polarisation of the chamber (10) and to the charges generated by the radiation pulse. The invention also concerns the related control method.

Abstract: 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).

Abstract: The present invention concerns a device for shaping an electron beam of a machine for intraoperative radiation therapy (IORT—Intra Operative Radiation Therapy) using a tubular applicator (3) having a duct through which the electron beam is transmitted, the device being characterised in that it comprises a slab (1), provided with a hole (2) corresponding to the duct of the tubular applicator (3), and at least one planar element (10) comprising an upper plate (11) and a lower plate (12) removably attachable to each other through first mechanical coupling means (13), said at least one planar element (10) being removably attachable to the slab (1) through second mechanical coupling means (13, 14) so that the arrangement of said at least one planar element (10) with respect to the slab (1) is adjustable so as to define an aperture (20) of lower area than that of the section of the duct of the tubular applicator (3), the upper plate (11) of each planar element (10) being made of a first sterilisable biocompatible m
