CT equipment and radiation protection device thereof

Abstract

The invention discloses CT (Computed Tomography) equipment and a radiation protection device thereof. The radiation protection device comprises a plurality of radiation protection plates arranged on the shell wall of a shell (5) of the CT equipment, the radiation protection plates comprise a first radiation protection plate (2) and a second radiation protection plate (3), wherein the first radiation protection plate (2) is used for surrounding the inner wall of a middle hole (1) of the CT equipment, and an opening used for avoiding rays emitted by a ray source (6) of the CT equipment is formed in the first radiation protection plate (2); the second radiation protection plates (3) are used for being arranged in the middle hole (1), the number of the second radiation protection plates (3) is multiple, and the second radiation protection plates (3) are symmetrically arranged on the two sides of the opening; and the third radiation protection plates (4) are used for being arranged on the two sides of the machine shell (5). According to the radiation protection device, the radiation protection device is directly installed in the CT equipment, radiation pollution of the CT equipment to a tested person and accompanying persons near the CT equipment is directly reduced, and the radiation problem is solved.

Description

technical field [0001] The invention relates to the technical field of radiation protection equipment, in particular to CT equipment and a radiation protection device thereof. Background technique [0002] CT (Computed Tomography, computerized tomography) is an X-ray computerized tomography device, which belongs to the application of ionizing radiation in the medical field. With the deepening of the application of X-rays, radiotherapy, interventional radiology, nuclear medicine and radiodiagnosis have rapidly become indispensable and important elements, supporting the development of modern medicine. [0003] Since CT examinations may cause subjects to receive higher exposure doses, people have paid more and more attention to the potential radiation safety hazards of radiation doses caused by CT examinations to subjects. Studies have shown that X-ray radiation is harmful to the human body. Severe injuries can increase the incidence of various cancers and neurological disease...
