Description

Radiation protection device for medical examination

Technical Field

The invention relates to the technical field of CT medical examination, in particular to a radiation protection device for medical examination.

Background

Radiation protection has become a major problem and in a sense, many radiation protection items have been created. Therefore, we must protect against radiation to some extent. Therefore, we should follow the rationale of radiation practice, not only to prevent harmful decisive effects, but also to produce severe symptoms. Due to social and economic factors, radiation protection has started from reducing the harm of radiation to human health.

Radiation is used primarily in medicine, and in modern life and work environments, it is desirable to protect the health and safety of people, the public and their progeny who engage in radiological work. Therefore, proper radiation practice principles should be followed. Indeed, the goal of radioprotection is to protect the health and safety of the people, the public and their progeny who engage in radiological work, and the benefits of our radiation practice are social benefits.

In the current medical CT examination, more X-ray beam radiation is applied, the X-ray beam is used for scanning a certain thickness layer of a human body in CT, X rays penetrating through the layer are received by a detector, converted into visible light, converted into electric signals by photoelectric conversion, converted into numbers by an analog/digital converter and input into a computer for processing. The image formation is handled as a division of the selected slice into cuboids of the same volume, called voxels. The information obtained from the scan is calculated to obtain the X-ray attenuation coefficient or absorption coefficient for each voxel, and then arranged into a matrix, i.e., a digital matrix, which may be stored on a magnetic or optical disk. Each digit in the digital matrix is converted into small blocks with different gray scales from black to white, namely pixels, through a digital/analog converter, and the small blocks are arranged according to the matrix, namely the CT image is formed. Therefore, the CT image is a reconstructed image. The X-ray absorption coefficient for each voxel can be calculated by different mathematical methods.

However, the CT diagnostic examination is a double-edged sword. On one hand, the image can clearly distinguish the etiology and is an important diagnosis and treatment method; on the other hand, more and more research has shown that it is harmful to the human body and abuse may induce cancer. Children are sensitive to radioactive radiation, particularly the thyroid and gonads, etc. When fluoroscopy, radiography and CT examination are performed, cells are easily damaged along with the increase of radiation dose, and even gene mutation and canceration can be induced. At present, when a patient is subjected to CT examination, most of the patients cannot effectively protect other parts of the body outside the examination range or the protection equipment is not intelligent enough, so that non-examined organs are damaged, and the prior art lacks an effective means for corresponding protection. To this end, we propose a radiation protection device for medical examinations.
