Description
Technical Field
The utility model relates to the technical field of ray protection equipment, in particular to protection equipment of a CT machine, and specifically relates to a CT ray protection device which does not affect CT imaging quality and is more convenient to use.
Background
CT (Computed Tomography), i.e. electronic computed tomography, is the tomographic imaging of a human body with radiation. The human body has different tissues and organs and different X-ray absorption degrees, and finally, images with different densities can be formed, CT is used for checking all the organs of the human body according to the principle, and compared with the common X-ray checking, the resolution ratio of the human body for the diseases of all the organs is higher, the obtained imaging information is more, and the human body diagnosis method is more beneficial to the disease diagnosis. The exposure time of CT is longer and the radiation damage to the subject is larger than that of the common X-ray examination.
The primary ray from the CT bulb enters the limb, one part of the primary ray penetrates through the tissue, and the other part of the primary ray and the limb act to generate photoelectric effect, compton effect and the like, and the effects are performed simultaneously. The absorbed X-rays are emitted from the limb as two types of rays: (1) attenuated primary rays, i.e., useful rays with information; (2) the X-rays of the photoelectric effect are all consumed in the body. The compton effect X-rays are partly consumed in the body and partly become scattered rays.
Scattered radiation is also generated when X-rays are irradiated on a detector, a gantry, a building, and the like. In addition, X-rays are generated outside the focus of the CT bulb, and may be 25% of the original radiation, and the radiation energy is similar to the radiation scattered in the same direction. After the CT bulb tube is used, the anode target surface can crack to different degrees, and the longer the service time is, the more serious the anode target surface is. At this time, scattered radiation having a direction different from that of the main radiation is also emitted from the target surface.
Most of the scattered rays are inconsistent with the main rays in the advancing direction, and can radiate to the non-inspected part of the inspected person through the aperture of the CT machine and the housing of the machine frame, so that the damage to the inspected person is great.
Regulations clearly dictate that CT examinations must provide effective shielding of the non-scanned parts of the subject to avoid radiation damage. The common protective lead clothing is large in weight, the wearing block is inconvenient, and the protective effect is poor due to the fact that the protective parts are limited. Since the position of CT scanning is dynamically changed, the position shielded by the lead clothing cannot be dynamically adjusted during actual examination, so that the protection effect is very poor even if the lead clothing is used for shielding. If the lead clothing is not disinfected and sterilized in time, more serious potential safety hazards such as cross infection exist.
The existing integrated CT protection device in the market is provided with a physical connection component in the main ray advancing path, and can have a certain influence on the CT image quality. The integrated CT protection device can also reduce the aperture size of CT and influence the examination of the subject. When the head and other parts are scanned, the CT frame needs to be adjusted to a certain angle, and after the integrated CT protection device is used, the original function of the CT frame cannot be realized.
