Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] In the prior art, medical accelerators do not integrate CT functions, and the positioning and reset of the patient treatment center need to be carried out in a CT room with CT equipment. At the same time, a CT scan is required for the positioning and reset of the treatment center; Move from the CT room to the treatment room with a medical accelerator to verify the location of the treatment center. The location verification of the treatment center also requires a radiological scan, such as an IGRT (Image Guide Radiation Therapy) scan. If the location verification of the treatment center passes , then follow-up radiotherapy is carried out in the treatment room. If the location veri...

Abstract

The embodiment of the invention discloses a method for achieving the position verification of a treatment center, which is used for verifying the position of the treatment center, wherein the method comprises the following steps of: controlling the movement of a treatment bed so that a the second position marking device points to a mark point, and obtaining the first position of the mark point; reading the position difference value between the position of an initial mark center and the position of a planned treatment center, wherein the treatment bed is controlled to move to a first treatmentposition according to the position difference value, and the second position of the mark point is obtained through the first position of the mark point; according to the corresponding relation betweena treatment position and a CT scanning position, controlling the treatment bed to move to a first CT scanning position, obtaining a third position of the mark point through the second position of themark point, and carrying out CT scanning; determining the position of the a target treatment center in the CT image by using the third position of the mark point, and obtaining the position difference value between the position of the target treatment center and the position of the planned treatment center of the treatment plan image; controlling the treatment bed to move to a second treatment position based on the position difference value.

Description

technical field [0001] The present application relates to the technical field of medical equipment, and in particular to a method and device for verifying the location of a treatment center. Background technique [0002] A medical accelerator is a biomedical particle accelerator device used for radiotherapy of tumors. It is a device that irradiates tumors with high-energy X-rays to inhibit their growth and cause them to die. It is very important to improve the accuracy of radiation localization and avoid damage to normal cells around the tumor. Therefore, it is necessary to maintain high precision in the process of positioning, repositioning and position verification of the patient's treatment center before using a medical accelerator to perform radiation therapy on the patient. [0003] In the prior art, the reset and position verification process of the treatment center needs to be completed separately in the CT room with CT (Computed Tomography, computerized tomography) ...
