Abstract
A radiotherapy system, comprises an image acquisition module, a placement module used for placing an irradiated body, a treatment planning module used for formulating a treatment plan, a radioactive ray generation module used for generating radioactive rays, and a positioning module used for realizing automatic positioning of the placement module. The positioning module calculates an irradiation position of the placement module on the basis of the treatment plan generated by the treatment planning module.
Claims15
A radiotherapy system, comprising:
- an image acquisition module configured to acquire a medical image of an irradiated body;
- a placement module configured to place the irradiated body;
- a treatment planning module configured to formulate a treatment plan;
- a radioactive ray generation module configured to generate radioactive rays;
- and
- a positioning module configured to control positioning of the placement module, wherein the positioning module is configured to calculate an irradiation position of the placement module on the basis of the treatment plan generated by the treatment planning module.
An automatic positioning method of a radiotherapy system, wherein
- the radiotherapy system is provided with at least an image laser positioning device and an operation laser positioning device;
- and
- the automatic positioning method comprises the following steps:
- placing markers at positions where laser beams emitted by the image laser positioning device intersect with an irradiated body;
- acquiring a medical image of the irradiated body with an imaging device;
- acquiring a marker coordinate system and a planned beam coordinate system based on a treatment planning module;
- acquiring a first transformation matrix based on the marker coordinate system and the planned beam coordinate system;
- fixing the irradiated body on a placement table, and irradiating laser beams emitted by the operation laser positioning device onto the markers correspondingly;
- and
- defining a second laser coordinate system of the operation laser positioning device, and determining an irradiation position of the placement table based on the second laser coordinate system and the first transformation matrix.
