Movable CT device for radiotherapy

Abstract

The invention belongs to the technical field of CT devices, and particularly relates to a movable CT device for radiotherapy. The movable CT device comprises a scanning ring and a fixing frame; the scanning ring is connected to the fixing frame; universal wheels are fixedly connected to the four corners of the fixing frame; a cavity is formed in the bottom end of the fixing frame; a fixing box is fixedly connected to the side wall of the bottom end of the fixing frame; a motor is arranged in the fixing box; the output end of the motor is fixedly connected with a first rotating shaft; the first rotating shaft extends into the cavity, and the end part of the first rotating shaft is fixedly connected with a first bevel gear; a second rotating shaft is rotationally connected to the side walls of the two sides of the cavity; and the second rotating shaft is perpendicular to the first rotating shaft. The invention provides the movable CT device for radiotherapy, and aims to solve the problems that in the prior art, rollers are used for moving in the whole moving process of the CT device, then the whole CT device is fixed by fixing the rollers, but the rollers are in rolling friction on the ground after being fixed, so that the rollers are easy to shake, and the detection of the CT device is influenced.

Description

technical field [0001] The invention belongs to the technical field of CT devices, in particular to a movable CT device for radiotherapy. Background technique [0002] In the field of modern medical technology, CT scanning equipment is a frequently used detection equipment, which can assist doctors to make professional judgments on lesions and provide protection for patients' life safety. Radiation therapy, that is, radiotherapy, can use ionizing radiation produced by radiation to kill tumor cells in the lesion area of ​​the treatment object. Radiotherapy is one of the important means of cancer treatment, more than half of tumor patients need to receive radiotherapy. Among them, radiation is produced by radiotherapy equipment. Usually X (γ) rays, electron rays or proton rays are used to kill and damage tumor cells. The preparation stage of radiotherapy requires the use of CT devices. With the development of medicine and the health needs of the people, it is urgent to prov...
