Embodiment Construction

[0036] As can be seen from the figure, the device according to the present invention can be defined as a machine that generates electron and X-ray beams for IORT treatment. It includes an electronic pulse source 2 based on a Mather-type plasma focusing device. More specifically, the source 2 includes a vacuum chamber 4 that surrounds two cylindrical coaxial electrodes 6 and 8 separated by an insulator 10 that also encloses the bottom of the chamber 4.

[0037] The two electrodes 6 and 8 are connected to the capacitor bank 12 via a quick switch 14. More specifically, the capacitor 12 is connected upstream to the charging power source 15 and downstream through the fast switch 14 to the high-voltage high-current transmission line 16 which is connected to the electrodes 6 and 8. The quick switch 14 is connected to a suitable connector on its side (in Figure 5 Not marked in) is connected to the cooling circuit and connected to the power source 15 through a suitable connector 17 at i...

Abstract

Apparatus for the production of electron beams and of X-ray beams for interstitial and intra-operatory radiation therapy, characterized in that it comprises: as a pulsed source of electrons, a head (2) of the Plasma Focus kind, with a vacuum chamber (4) provided with a pair of cylindrical, coaxial electrodes (6, 8) to generate an electrical discharge, and with means to introduce at least one reaction gas into the chamber (4) an electrical circuitry feeding the source head, comprising a capacitor bank (12) with fast switches (14) and conductors (16, 21) connecting to the electrodes (6, 8) of the vacuum chamber (4); and an electron guide (22), coaxial to the electrodes, departing from the source head to right near the irradiation site an armored gantry (26, 28) with high voltage cables and means for the suspension and movement of the head (2).

Description

Technical field [0001] The present invention relates to a device for generating electron beams and X-ray beams for interstitial and intra-operatory radiation therapy, which is more commonly referred to as IORT (intra-operative radiation therapy). treatment). More specifically, the present invention relates to an IORT device using a plasma focusing type machine, which is coupled to an electron guide that transmits the beam directly to the electron or photon X-ray radiation treatment to be used at a low energy, extremely high dose rate Organization. Background technique [0002] It is known that a Mather-type plasma focusing machine (JW Mather, in: Methods of experimental physics, Vol. 9, Part B. Plasma Physics, Eds. RH Lovberg and HR Griem-Academic Press, New York, 1971- Chapter 55) Capable of generating, accelerating and confining plasma, which causes a thermonuclear reaction under suitable working conditions to generate radiation and nuclide and / or other subatomic particles. ...
