Background

CT scanning is an important clinical examination means, and utilizes radioactive rays and a detector to carry out section scanning around a certain part of a human body one by one, and obtains radioactive ray absorption numerical values of all points on a scanning layer through calculation processing of a computer, and the data form a matrix of an image, so that the CT scanning is used for assisting a doctor to diagnose diseases, and has the advantages of simple and convenient operation, high accuracy, clearer scanned image and the like. While providing assistance in disease diagnosis, CT scanning causes some damage to the human body, and as CT technology continues to be widely used, such damage is increasingly well recognized. The international radiation protection committee has proved that the risk of carcinogenesis of the examinee due to radiation is obviously improved when a CT scan is carried out for the whole body examination. In addition, during the scanning process, the radioactive rays are repeatedly emitted and refracted in the scanning space to generate a large amount of rays, the body of the detected person is inevitably repeatedly irradiated by the rays, and after being absorbed by human tissues, the human tissues are damaged, particularly the gonads, the thyroid glands, the lungs, the mammary glands and the like of the person; it has been confirmed that various tumors are induced by exposure of human tissues to radiation.

During CT scanning, X-rays radiate a human body, which seriously affects the health of the human body, so that a plurality of CT radiation-proof scanning devices are provided, the existing radiation-proof scanning devices adopt lead to block the X-rays to prevent radiation, but the blocking is limited after all, and a part of the X-rays can also radiate the human body; the existing radiation protection device only has one radiation protection guard plate, and the radiation protection effect is poor.

Furthermore, the baffle adopts the lead plate, the atomic number and the density of lead are relatively high, X rays can be prevented from passing through, but not all light can be prevented, the penetrated light is diffused through the concave surface and does not irradiate on a human body, and the radiation-proof effect is excellent.

Furthermore, the two baffles can slide back and forth in the sliding groove and can be detached; when CT irradiation examination is needed to be carried out on the chest, the two baffle plates are slid to cover the head and the legs of a patient, and the use is convenient.

The utility model has the advantages that: a novel radiation protection CT scanning device has the following advantages:

1. the two baffles can slide in the sliding groove, when CT examination is needed to be performed on the middle part of a human body, the baffles slide to the two ends of the human body to prevent X-ray irradiation, and the two baffles are detachable and convenient to use;

2. the baffle adopts a lead plate, the atomic number and the density of lead are relatively high, and the lead can block X rays so as to reduce the radiation to a human body;

3. the baffle is arranged in a concave surface shape, the concave surface has diffusion left and right to light, the baffle penetrating X rays diffuses under the action of the concave surface, the X rays do not penetrate through the center of the baffle, and the radiation-proof effect is good.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
