Radiation protection device for CT (Computed Tomography) examination

Abstract

The invention relates to the technical field of CT examination, in particular to an anti-radiation device for CT examination, which comprises a frame body, a base plate and a connecting column, the base plate is arranged at the bottom end of the frame body, and the connecting column is fixedly mounted on the outer surface of the base plate. Through the fixed frame, the sliding mechanism and the protective lead cloth, when a patient is subjected to CT examination, after the patient lies flat above the examination bed, parts which are not examined need to be shielded and covered, so that other parts of the body are prevented from being damaged by radiation, firstly, through rotation of a rotating wheel, after a threaded lead screw is rotated, the threaded lead screw is driven to rotate, and then the CT examination is carried out on the patient; the lead cloth can be telescopically adjusted with the screwing seat, so that the telescopic displacement of the screwing seat is adjusted, and the two sides of an examined part are shielded, so that the lead cloth can isolate most of radiation which directly irradiates other parts of the body of a patient when the CT radiation device is used for radioexamination, and damage to the parts of the human body due to scattering of the radiation is prevented.

Description

technical field [0001] The invention relates to the technical field of CT examination, in particular to a radiation protection device for CT examination. Background technique [0002] CT is a full-featured disease detection instrument. It is the abbreviation of computerized X-ray tomography. CT inspection is based on the difference in the absorption and transmittance of X-rays by different tissues of the human body. Measurement, and then input the data obtained by the measurement into the electronic computer. After the electronic computer processes the data, it can take a cross-sectional or three-dimensional image of the inspected part of the human body, and find small lesions in any part of the body. [0003] At present, when performing physical examination, it is often necessary to use CT to check the diseased position on the body. When the patient is tested by CT, it is often necessary for the patient to cover a layer of lead cloth on the body position that does not need ...
