Embodiment Construction

[0041] Aiming at the problems existing in the prior art, the inventor proposes a new intensity modulation scheme, which achieves the purpose of radiation intensity modulation by improving the treatment target itself. In this regard, a manufacturing method for the new treatment target and a radiotherapy device including the treatment target are also proposed.

[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] refer to figure 1 , figure 2 , the manufacturing method of the therapeutic target for intensity modulation of the present embodiment comprises:

[0044] Execute step S1, according to the anatomical information of the area to be treated, obtain the first intensity distribution of the radiation dose of the area to be treated 1, wherein the area to be treated 1 includes the tu...

Abstract

The invention relates to radiological treatment equipment, a therapeutic target, a manufacturing method of the therapeutic target and a radiological treatment method. The thickness distribution of the therapeutic target along a linear direction is correlated with the distribution of the radiological dose intensity in an area to be treated, wherein the correlation mode lies in that the dose intensity of first intensity distribution is inversely correlated with the thickness of the therapeutic target along a linear direction. In the radiological treatment process, the radiological dose intensity of treatment ray transmitting from the thinnest part of the therapeutic target is highest so as to realize radiological treatment. According to the scheme, through improving the therapeutic target per se to realize the purpose of intensifying therapeutic ray, no extra intensifying equipment is introduced, and the errors caused by the intensifying equipment can be avoided so as to ensure that the dose intensity distribution of actual therapeutic ray meets the preset dose intensity distribution requirement. In addition, the therapeutic target solves the problem that existing intensifying equipment is complicated in structure, high in fault rate and high in maintenance cost, and is simple in self structure and relatively low in production cost.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a radiotherapy device, a treatment target and a manufacturing method thereof, and a radiotherapy method. Background technique [0002] During therapeutic irradiation, due to the different shapes and thicknesses of tumors, the dose intensity of therapeutic radiation irradiated on the tumor is required to be non-uniformly distributed, and the dose intensity distribution of therapeutic radiation needs to be adjusted according to the three-dimensional shape of the tumor. In addition, there is usually no absolute boundary between tumor tissue and healthy tissue. When a large dose of therapeutic radiation is used to irradiate a tumor for precise treatment, sometimes a smaller dose of therapeutic radiation is irradiated to the tissues around the tumor. , while for other tissues that are relatively far away from the tumor, it is necessary to avoid damage by the treatment rays. Therefore, d...
