X-ray perspective apparatus is a machine used in medical field to conduct a fluoroscopic examination on a object by X rays, such as orthopaedic perspective apparatus, dental perspective apparatus. The mainframe of X-ray perspective apparatus is made up of the transmitter and the receiver. The transmitter first transmits X rays through objects, then the receiver receive the X rays and process them into images, so a X-ray perspective apparatus can perceive different objects to capture images. Meanwhile, X-ray can inhibit, destroy or even kill the biological cells, which results in varying degrees of changes in body physiology, pathology and biochemical aspects. Therefore, in the case of using a X-ray perspective apparatus, it should take certain protective measures to avoid the harm of radiation on the human body, such as the use of tungsten alloy shielding for X-ray perspective apparatus.

X-ray perspective apparatus is widely used in the medical diagnosis due to the penetrating power, ionization effect, fluorescent effect, differential absorption and other characteristics of X rays. The penetrating power of X rays is related to the density of objects. When X rays penetrate the human body, it can be absorbed in different degree, such as the skeleton absorbs more doses of X rays than muscles. The discrepancy in the doses of X rays after passing through human body will be embodied in the strength of fluorescence effect on the fluorescent screen or the filmstrip, thus the doctors can judge if one part of the human body is normal by comparing the shadow of different density on the fluorescent screen and in combination with clinical manifestations, laboratory results and pathological diagnosis.

X-rays can used for treating some diseases, especially the treatment of cancers. However, the use of X-rays also brought some problems to patients (such as hair loss, skin burns) and the staffs (such as vision disorders, leukemia). Tungsten alloy shielding for X-ray perspective apparatus has high density, extreme hardness, excellent strength, great shielding performance and other characteristics, which make it shield and absorb radiation in a high degree, to prevent bodily harm.
