Problems solved by technology

In the clinical process, patients participating in radiotherapy, especially those in the advanced stage (stage III, IV), are relatively weak, and it is difficult to obtain accurate gating signals. Especially during the treatment process, patients need to hold their breath all the time, which is very unfavorable for clinical treatment

Abstract

An image fusion-guidance device based on respiratory gating and CT includes a CT scanner, which is provided with a respiratory gating device and a gantry. A patient couch and a treatment head are provided in the gantry. A respiratory gating sensor is provided on the patient couch. The respiratory gating device is connected to a CT image workstation and an image fusion acquisition device via synchronization signal lines. The image fusion acquisition device is connected to an image fusion-processing device, which is connected to an image fusion display device. The treatment head is connected to a beam output controller via a beam output control line. The present application further provides an image fusion-guidance method based on respiratory gating and CT. In the guiding process, the patient is only required to hold the breath once, and then the patient breathes freely in the subsequent treatment.

Description

Technical field [0001] The invention belongs to the technical field of medical mechanical equipment, and relates to an image guiding device and a method for fusion of respiratory gating and CT images. Background technique [0002] At present, the development of medical electronic mechanical equipment has greatly helped the development of advanced treatment technology, but there is still a lot of room for improvement in certain treatment methods. For example, when a doctor performs radiotherapy on a patient, it is generally necessary to position the patient and transfer the bed to a designated position. The technician often cannot know the true position of the patient lying on the treatment bed, such as the distance between the human body and the rotating gantry and the treatment head. . In the current radiotherapy process, the patient's breathing will cause the tumor location and important organs to move, which may result in low-dose irradiation of tumor interest areas or high-d...
