Background
With the development of modern computing technology and image processing technology, the CT apparatus has been updated from the first generation to the fourth generation, and its contribution to the human health examination is more and more significant. However, with the rapid development of CT, the number of people and the number of times of examination of each part of the body using CT equipment are increasing, and as a result, the number of people who receive ionizing radiation and the annual average radiation dose of a single person brought by CT examination are also increasing, and the judgment of medical ionizing radiation hazard by learners is one of the problems affecting the public health in the future, and is not negligible.
In CT examination, because the tissue structures of various parts of the body are different, the sensitivity to radiation is also different, the degree of response of the body to radiation is also strong or weak, and tissues with high radiation sensitivity are easily damaged. Relevant regulations state that shielding protection is necessary for radiation sensitive tissues.
Protection has also been increasingly studied in recent years due to the greater tissue sensitivity and increased protection that is required for children relative to adults. For example, proper neck protection is necessary for children undergoing CT craniocerebral examinations. In practice, people protect the neck of a child with a lead skin or a protective neckerchief in order to reduce the radiation of scattered rays to the thyroid gland. When CT examination is performed on lumbar vertebra, abdomen, pelvis, ilium, sacrum, coccyx, urinary tract, small intestine, upper thigh and other parts, a method of shielding and covering with lead is used for protecting sensitive parts such as testis, ovary and the like, and lead clothes with a large enough area are manufactured to expand the shielding range as much as possible.
To sum up, among the current CT scanning process, for the patient dresses plumbous clothing and avoids the radiation, although played certain guard action, plumbous clothing weight is great, dresses inconveniently, has prolonged CT scanning's operating time, is unfavorable for patient and medical personnel's healthy, consequently, develops more intelligent, accurate, high-efficient protector more and more important.
