Problems solved by technology

However, whether the collimator is loaded with a rotating collimator or a moving collimator, due to the limitation of the treatment space, the number of available collimators is very limited, which greatly reduces the clinical use of the focusing treatment head. flexibility

Abstract

A focussed radiotherapy apparatus (100) and a radiation therapy device (200), the focussed radiotherapy apparatus (100) at least comprising: a source body (10), provided with a plurality of radiation sources (11); a pre-collimation body (20), fixedly connected to the source body (10), the pre-collimation body (20) comprising a plurality of pre-collimation holes, the pre-collimation holes corresponding to the radiation sources (11) in a one-to-one manner; a collimation body (30), covering the source body (10) and the pre-collimation body (20) and rotating with respect to the source body (10) and the pre-collimation body (20), the collimation body (30) comprising at least one curved surface, a plurality of groups of collimators, having different specifications, and shielding positions (31) being arranged on the curved surface, each group of collimators and / or shielding positions (31) being arranged in correspondence with the radiation sources (11), the collimation body (30) rotating to switch different groups of collimators and / or shielding positions (31) to be aligned with the radiation sources (11) so as to obtain different field sizes and / or implement at least partial shielding of the source body (10); a switch body (40), arranged on an outer side of the collimation body (30) and moving with respect to the source body (10), the pre-collimation body (20) and the collimation body (30) so as to enable rays of the radiation sources (11) to be focussed or shielded. The invention also provides a radiation therapy device.

Description

technical field [0001] The invention relates to a medical device, in particular to a focused radiotherapy device and radiotherapy equipment using the focused radiotherapy device. Background technique [0002] In the radiation therapy industry, the technology of using Go-60 for focused radiation therapy is quite mature. However, due to the particularity of the radiation source of Go-60, it is necessary to set up a thick and heavy shielding mechanism to prevent the radiation from leaking out. Moreover, the existing focus therapy head usually adopts a structure in which shielding body, source body, and collimator are arranged in sequence from outside to inside, which makes the structure of the focus therapy head often very complicated and bulky. In addition, it is usually necessary to use as many collimator combinations as possible in the focus therapy head, so as to obtain more collimation aperture combinations, so as to meet the requirements of different radiation field size...
