Embodiment Construction

[0022] An X-ray target assembly for various applications including medical radiation therapy according to an embodiment of the present invention will be described below with reference to FIGS. 3 and 4 . X-ray target assembly 200 is similar in some respects to x-ray target assembly 100 and, accordingly, like numbers are used to refer to like parts.

[0023] X-ray target assembly 200 includes a stainless steel cylindrical housing 202 supported by a pair of tubes 103 . Inside the housing 202 , a graphite cylindrical electron absorber 104 is mounted in the center of the housing 202 and supported on an annular bottom part 106 of the housing 202 . The ring-shaped bottom part 106 is connected to the housing 202 by mechanical fixing means, such as screws in the opening 108 of the insertion part 106 and the opening of the housing 202 .

[0024] As shown in FIG. 4 , an annular groove 210 is formed in the housing 202 . On top of recess 210, a copper heat dissipating top lid 212 of hous...

Abstract

An x-ray target assembly including a housing having a recess, a cooling fluid contained within the recess and an x-ray target attached to the housing, wherein the x-ray target does not directly contact the cooling fluid.

Description

technical field [0001] The present invention relates to X-ray target assemblies. The X-ray target assembly is preferably used in a charged particle accelerator on a radiotherapy apparatus. Background technique [0002] Electron bombardment of X-ray target assemblies used in charged particle accelerators is known to generate X-rays. Figures 1 and 2 show embodiments of known X-ray target assemblies for use on radiotherapy apparatus manufactured by Siemens Medical Solutions of Concord (California) and sold under the trademarks Mevatron and Primus. The X-ray target assembly 100 includes a stainless steel cylindrical housing 102 supported by a pair of tubes 103 . [0003] Inside the housing 102 , a graphite cylindrical electron absorber 104 is mounted in the center of the housing 102 and supported on an annular bottom part 106 of the housing 102 . The annular bottom part 106 is connected to the bottom side edge of the housing 102 by means of mechanical fastening means, such as...
