Embodiment Construction

[0011] Embodiment of the invention

[0012] The raw materials used in the present invention are commercially available aluminum, zinc, copper, manganese and iron, all of which are powdery, requiring material purity to reach more than 96%, and weighing accuracy of 99% ± 1%. After all materials are weighed according to the formula, fully Stir evenly, and then make a filter by hydraulic method or high-temperature sintering method. The diameter, length, width and thickness of the filter are exactly the same as those used in the current X-ray machine, and the size error of the specification is less than ±0.05mm. The sintering temperature should not be too high, and should be controlled at 540±30°C to ensure the properties of the metal elements as much as possible. When the filter is manufactured by hydraulic method, its hardness is required to be 4-5 degrees. As long as the operation is strictly in accordance with the process requirements, a qualified filter with pressure resistanc...

Abstract

The present invention relates t oa soft X-ray filtering sheet for medical X-ray apparatus. It is made up by using aluminium, zinc, copper, manganese and iron as raw material components according to a certain weight ratio through the process of hydraulic-pressing or sintering treatment. Said invented product can filter off soft X-ray, only allow the hard X-ray to pass through, so that it not only can reduce radiation damage to human body, but also can obtain clear roentgenogram, and can reduce radioactive rays quantity by above 50%. Said invention is low in cost, can be used in the fields of fluoroscopy, CT diagnosis and cardiac catheterization, etc..

Description

field of invention [0001] The invention belongs to a soft X-ray filter used in a medical X-ray machine. Background of the invention [0002] Using X-rays to check diseases is a common clinical diagnosis method. Since Rontgen discovered X-rays in 1895, it has been widely used in various fields of clinical medicine, and has also penetrated into various basic medical research disciplines. It has become an important part of modern clinical medicine. With the vigorous development of the world's medical and health services, X-ray machines have become increasingly popular, and have played an irreplaceable role in many common diseases, frequently-occurring diseases, occupational diseases and endemic diseases that endanger people's health, and have become one of the indispensable diagnostic methods. one. However, with the widespread application of medical X-ray machines, the ionized biological effects of X-rays on the human body, and thus the damage to the biological body, have bec...
