Abstract

The invention relates to a control device and method for adjusting the position of an X-ray tube source in cone beam CT and relates to the technical field of medical apparatus, in particular to the technical field of Elekta linear accelerators. The device comprises a first outer socket bar and a second outer socket bar; the first and second outer socket bars disposed in parallel are used for adjusting the position of an X-ray tube source in cone beam CT; a first internal screw rod is disposed inside the first outer socket bar; a second internal screw rod is disposed inside the second outer socket bar; the first and second internal screw rods are both connected with an adjusting device which is connected with a drive device. The control device and method allows for remote control and allows the tube source in cone beam CT motion to be automatically controlled highly efficiently.

Description

[0001] technical field [0002] This application relates to the technical field of medical devices, in particular to the technical field of Elekta linear accelerators. [0003] Background technique [0004] At present, linear accelerators are the most used in radiotherapy, especially for tumor radiotherapy. A linear accelerator is a large-scale medical device used for cancer radiation therapy. It generates X-rays and electron beams to directly irradiate tumors in the human body, so as to achieve the purpose of eliminating or reducing tumors. A linear accelerator is an electromagnetic device that artificially accelerates various types of charged particles to higher energies with the help of different forms of electric fields. [0005] Cone beam CT movement is the most used in oral and cranial imaging equipment. Because cone beam CT movement can scan multiple layers of tissue at one time, it greatly improves the speed of data acquisition and the utilization rate of X-rays. I...
