MOBILE SYSTEM FOR ELECTRON BEAM INTRAOPERATIVE RADIATION THERAPY

摘要

The present invention is concerned with an electron beam intraoperative radiation therapy system using race-track microtron. In the preferred embodiment, the electron beam intraoperative radiation therapy system comprises a race-track microtron placed in a housing playing the role of the vacuum chamber, which is supported by a positioning means providing its motion with six degrees of freedom with respect to a patient. The positioning means is a part of a mobile mechanical structure which houses an ion pump, a microwave source, waveguide elements, a modulator with a pulse transformer and a cooler. The intraopearative radiation therapy system comprises a tube-like unit which couples the vacuum chamber with the mobile supporting mechanical structure and provides three functions, namely pumping out of the air from the vacuum chamber, feeding of the race-track microtron accelerating structure with radiofrequency power and rotation of the vacuum chamber with respect to the horizontal axis of the unit.
