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 performed in the treatment room. If the location verifi...

Abstract

The embodiment of the present application discloses a method for verifying the position of the treatment center, which is used to verify the position of the treatment center. The method includes: controlling the movement of the treatment bed so that the second position marking device points to the marking point, and obtaining the first position of the marking point. Position: read the position difference between the initial mark center position and the planned treatment center position, control the treatment bed to move to the first treatment position according to the position difference, and obtain the second position of the mark point from the first position of the mark point; according to The corresponding relationship between the treatment position and the CT scanning position, control the treatment bed to move to the first CT scanning position, obtain the third position of the marking point from the second position of the marking point, and perform CT scanning; use the third position of the marking point to Determine the position of the target treatment center in the image, and obtain the position difference between the target treatment center position and the planned treatment center position in the treatment plan image; according to the position difference, control the treatment bed to move to the second treatment position.

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) ...
