Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] In the process of radiotherapy for tumors (hereinafter referred to as radiotherapy), involuntary movement of the patient, respiration and organ peristalsis of the patient will cause the position of the tumor to change during each radiotherapy. In order to reduce the treatment error, adaptive radiation therapy (English: adaptive radiation therapy; ART for short) is used, that is, the tumor and normal organs are monitored in real time by imaging equipment when the patient is undergoing treatment, and according to the monitored organ position Adjust the treatment conditions so that the irradiation field moves with the movement of the target area, that is, modify the treatment plan according to the movement of the target area, ...

Abstract

The present application discloses a radiotherapy plan creating method, a radiotherapy plan system, and a radiotherapy system, and belongs to the field of medical technology. The method comprises: acquiring a tumor target area scan image and an initial radiotherapy plan; establishing a radiotherapy plan library according to the tumor target area scan image and the initial radiotherapy plan, whereinthe radiotherapy plan library includes a plurality of radiotherapy plans different from the positions of the tumor target area scan image, and the radiotherapy plan includes a plurality of radiotherapy plan segments associated with time periods. The radiotherapy plan creating method solves the problem that the radiotherapy plan cannot be adjusted according to the position of the tumor in real time and radiotherapy has a low accuracy, and improves radiotherapy precision. The method is used for creating a radiotherapy plan.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a radiotherapy planning method, a radiotherapy planning system and a radiotherapy system. Background technique [0002] With the development of medical technology, the requirements for the accuracy of radiotherapy are getting higher and higher, that is, the requirements for the accuracy of beam irradiation on the tumor target area during radiotherapy are getting higher and higher. [0003] Before treating the tumor in the patient's body, it is necessary to determine the shape and position of the tumor in the patient's body, and formulate a treatment plan based on the shape and position, that is, to determine the size of the collimation channel in the radiotherapy equipment and the dose rate received by each position of the tumor , the position of the rack in the radiotherapy equipment, etc., and then the tumor can be treated according to the treatment plan. However, d...
