What do you want to check for? Full-name fluorescent perspective, commonly used for x-rays. It uses the properties of x-rays with permeability, fluorescent and photographic effects to produce images on the screen of humans, and the x-rays differ in the amount of x-rays that reach the screens, creating different images of black and white contrasts to provide a basis for doctors ' diagnosis, given the density and thickness of human tissues and the degree to which x-rays are absorbed when they penetrate different tissues of humans。
X-ray penetration into the human body would have a certain biological effect and, if the x-ray exposure was excessive and exceeded the permissible radiation, it could result in a radiological reaction or even a degree of radiation damage. However, if x-rays are within permissible limits, the impact is generally small. Over the past decade, improvements in x-ray equipment, the use of high kilovolt technology, image enhancement technology, high-speed sensor screens and fast x-ray sensor film have resulted in a significant decrease in x-ray radioactivity and a diminishing potential for radiation damage。
The radiation levels of chest perforation are the largest in x-rays, and a chest perforation is equivalent to 10 x-rays. However, breast perforation is also generally done for dozens of seconds, so the risk to the human body is very limited. There is little apparent harm to an adult doing a chest permutation at a time, but every effort is made to replace a chest permafrost with a photograph. The voltage and currents used for chest penetration are significantly weaker than for filming, and because of weak strength, rays cannot penetrate the body as quickly as they do, they pass through the body for relatively longer periods and are absorbed at more doses. Moreover, the clarity and accuracy of the chest is not as good as the results of the film. However, the chest penetrators have characteristics that are simple, operational and less expensive (generally between $6 and $10 at a time) and can be immediately concluded。
Which diseases are to be checked for chests and how are they protected
The chest perforation is primarily used for the diagnosis of lung diseases, heart size, ribs, pleural membranes, chest wall splitting, bronchial tubes. In order to reduce the damage caused by x-rays, it is not appropriate for patients to have enough chest-to-heart examinations and for repeated examinations to be performed in the short term, especially when chest-to-heart tests are required to be longer and more careful。
The above is a description of what “the choice of chest perforation is” and it is believed that people already know it, and that it is not the right thing to do. It must be done under the guidance of a doctor, so that they do not have to do it as much as possible, in order to avoid serious consequences。
