Respiratory gating and CT image fusion image guidance device and method thereof

Abstract

The invention discloses a respiratory gating and CT image fusion image guidance device, which includes CT imaging equipment. The CT imaging equipment is provided with a respiratory gating sensing device and a CT cavity. The CT cavity is provided with a treatment bed required by the patient and The treatment head is equipped with a respiratory gating sensor on the treatment bed. The respiratory gating sensing device is connected to the CT image workstation and the image fusion acquisition device through a synchronous signal line. The image fusion acquisition device is connected to the image fusion processing device, and the image fusion processing device is connected to the image fusion display. Device; wherein the treatment head is connected to the beam output controller through the beam output control line. During the guidance process of this invention, the patient only needs to hold his breath once after starting the respiratory gating device, and later treatment only requires normal breathing. At the same time, during the guidance process, the registration and fusion algorithm is introduced to make the guidance positioning more accurate, and the registration is The introduction of fusion algorithms can improve guidance efficiency, thereby reducing treatment time and reducing patient radiation time.

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...

AI Technical Summary

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
