Problems solved by technology

However, the pre-equipment cost of linear accelerator radiation therapy is relatively high, while the fixed asset investment of cobalt-60 therapy machine radiation therapy is relatively low. Therefore, some manufacturers and consumers are still willing to choose cobalt-60 therapy machine
However, the existing cobalt-60 treatment machine has a complicated structure and is very heavy, which is not conducive to installation and transportation

Abstract

Provided is a conformal intensity-modulated radiation therapy device, comprising: a housing, formed with an accommodating space and a shielding cavity; shielding material, filled within the shielding cavity; a rotary source-carrying body, accommodated within the accommodating space; a shielding rod, accommodated within the rotary source-carrying body; a source body, accommodated at a bottom end of the shielding rod and used for carrying a radiation source; a first driving portion, arranged on the housing and driving the rotary source-carrying body to rotate around a rotary axis thereof so that the radiation source switches between an open source position and a closed source position; a pre-collimation body, arranged at an emission end of the radiation source and comprising a collimation hole, the collimation hole directly facing the radiation source when the radiation source is in the open source position; a shielding door, arranged at the side of the pre-collimation body away from the radiation source and directly facing the radiation source; a multi-leaf collimator, arranged outside the housing and directly facing the shielding door. Also provided is a conformal intensity-modulated radiation therapy system.

Description

technical field [0001] The invention relates to the field of radiotherapy equipment, in particular to a conformal intensity-modulated radiotherapy device. Background technique [0002] Three-dimensional conformal radiation therapy is a high-precision radiation therapy. CT images are used to reconstruct the three-dimensional tumor structure. The distribution shape of the area is consistent with the shape of the target area in three-dimensional directions (front-back, left-right, and up-down directions), and at the same time reduces the dose received by normal tissues around the lesion. [0003] For the three-dimensional conformal radiotherapy system, the treatment head is the core part. Most of the existing conformal treatment heads use medical linear accelerators as radiation sources. However, the pre-equipment cost of linear accelerator radiation therapy is high, and the fixed asset investment of cobalt-60 therapy machine radiation therapy is low. Therefore, some manufact...
