Embodiment Construction

[0040] 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.

[0041] 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 and device for verifying the position of a therapeutic center, and the method and device are used for achieving the more convenient position verification of a therapeutic center of a medical accelerator. The method comprises the steps: controlling a treatment bed to move to an initial position, wherein the initial position and the position of an initial mark center have the corresponding relation; reading the position difference between the position of the initial mark center and the position of a planned therapeutic center, controlling the treatment bed to move to the target position from the initial position according to the position difference, so as to enable second position marking equipment to point to the position of a target mark point, wherein the position of the target mark point is used for setting a mark point; controlling the treatment bed to move to a CT scanning position for CT scanning to obtain the CT data outputted through the CT scanning; determining the position of a target therapeutic center through the position of the mark point in the CT data, and obtaining the difference between the position of the target therapeutic center and the position of the planned therapeutic center; controlling the treatment bed to move to the target position when the difference between the position of the target therapeutic center and the position of the planned therapeutic center is less than a first threshold value, and completing the verification of the position of the treatment center.

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) ...
