DEVICE FORMATION OF THE FORM OF THE ELECTRON BEAM OF THE DEVICE FOR INTRAOPERATIVE RADIOTHERAPY THERAPY

摘要

The present invention relates to a device for forming the electron beam shape of an apparatus for intraoperative radiation therapy (IORT - intraoperative radiation therapy), equipped with a tubular applicator (3) with a channel through which the electron beam passes, the device is characterized in that it contains a plate (1) with an opening ( 2) corresponding to the channel in the tubular applicator (3), and at least one planar element (10) comprising an upper plate (11) and a lower plate (12) that can be detachably attached to each other by the first mechanical connecting means (13), the at least one planar element (10) can be detachably attached to the plate (1) by means of the second mechanical connecting means (13, 14) so that the location of the specified at least one planar element ( 10) relative to the plate (1), it was possible to adjust the hole (20), the area of which is less than the cross-sectional area of the channel of the tubular applicator (3), the upper plate (11) of each planar element (10) is made of the first sterilized biologist eski compatible material with a first atomic number, the bottom plate (12) of each planar element (10) is made of a second sterilizable, biocompatible material with a second atomic number that is larger than the first atomic number, while the bottom plate (12) attenuates the x-rays generated top plate (11). The present invention also relates to a method for automatically calculating the distribution of the dose emitted by the IOLT apparatus through an electron beam-forming device.
