X-ray computed radiography (CR) is kind of digital imaging technology using tungsten alloy imaging plate (IP) as carrier for X-ray image. The most important characteristic of CR system is that it is made of tungsten alloy IP, the new generation for X-ray image which is different from film, carrier utilized by traditional shadowgrap. The new carrier has high sensitivity and latitude to X-ray.

But tungsten alloy IP cannot produce visible light directly after absorbing X-ray. It produces stable sub-image and store inside crystal of tungsten alloy IP after collecting analog signal of X-ray. Sub-image can be read when being scanned by photoluminescence. Conversion of signal output by tungsten alloy IP is finished. Then signal forms digital image after being dealt with by computer. The final image can be shown on fluorescent screen or printed on film, heat sensitive paper or others, besides storing in disc and system.

Focusing ring used to adjust the lens so that the subject appears sharp on the film or CCD. Most cameras now have automatic focus (AF), some have manual focus override (MF) and some have a fixed focus (F) lens that ensures things from about 1.5 meters to infinity are relatively sharp. A few cameras have a power focus (PF), which is a manual method, using a motorized tungsten alloy radiation focusing ring. Lenses with a ring that allows a good grip make tungsten alloy radiation focusing ring easier to adjust and focus manually.

A low-cost lens doesn't have a tungsten alloy radiation focusing ring. Found in very basic cameras. The lens is set to a distance of around three meters and relies on the depth of field to bring everything from about one and a half meters to infinity. The quality is always a compromise over a lens with adjustable focusing. Tungsten alloy radiation focusing ring is good to our health.

An optical device is built into older cameras or added as an attachment. That is used to work out the subject distance by comparing two viewpoints. You see a double image and adjust the lenses until the images form one which gives a distance reading that can then be transferred to the focusing ring.

As we know, all microelectronic have radiation when we used. In order to resistant radiation from these products, we have to protect measures to prevent it. Tungsten alloys is a best choices for tungsten alloy radiation focusing ring. Compared to traditional radiation shielding materials, tungsten alloy radiation focusing ring provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy reliable radiation focusing ring properties.

To protect our health from the radiation, tungsten X-ray protection apron becomes more and more popular in medical areas. With the development of our daily life, more and more machines are used by people both in medical and other industries which brought much more radiation for us than ever, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. they are very harmful to our body, there also comes a lot of shielding made by tungsten heavy alloy such as tungsten X-ray protection apron from tungsten powder which is very popular in medical especially when the patient makes a panorama X-ray.

Tungsten X-ray protection apron made from tungsten powder equally protects against the radiation, as tungsten powder is high density with small volume, good corrosion resistance, and high temperature resistance, non-toxic and environmentally friendly.
