Patent number: 9750957Abstract: A charged particle irradiation system is capable of shortening the irradiation time and the treatment time by performing efficient irradiation even when irregular variation occurs in the irradiation object during the gating irradiation. The extraction of the beam is stopped upon reception of a regular extraction permission end signal which is outputted based on a regular movement signal. An extractable state maintaining function operates upon the reception of the extraction permission end signal. When a preset standby time elapses without receiving an extraction permission start signal again during the standby time, the extractable state maintaining function finishes its operation and a charged particle beam generator decelerates the beam. Also, the extraction of the beam is stopped due to reception of an irregular extraction permission end signal during the irradiation. When the extraction permission start signal is received again during the standby time, the extraction of the beam is restarted.Type: GrantFiled: June 1, 2015Date of Patent: September 5, 2017Assignee: Hitachi, Ltd.Inventors: Yusuke Fujii, Toru Umekawa, Masumi Umezawa, Hiroki Shirato, Kikuo Umegaki, Naoki Miyamoto, Taeko Matsuura

Publication number: 20170243665Abstract: A structure configuring a ridge filter has line symmetry about a line vertical to a depth direction passing the center of the structure. A small structure obtained in such a way that the structure is divided by this line has a bilaterally asymmetric shape about a center line in an iterative direction, and has a point symmetric shape about an intersection between the center line in the iterative direction and the center line in the depth direction. Thicknesses in the iterative direction of an uppermost stream surface and a lowermost stream surface in the depth direction are equal to each other. The structure is configured so that a thick portion in the iterative direction of the uppermost stream surface and the lowermost stream surface is not present in the depth direction.Type: ApplicationFiled: February 21, 2017Publication date: August 24, 2017Inventors: Taisuke TAKAYANAGI, Shinichiro FUJITAKA, Chihiro NAKASHIMA, Tomoki MURATA, Taeko MATSUURA, Naoki MIYAMOTO, Kikuo UMEGAKI, Yuichi HIRATA
