The Essence Of Digital X Ray In Modern Medicine

By Nicole Guy


The idea of digital x ray imaging has kick started the demise of the conventional radiography. Instead of the usual photographic film, special sensors are used. The captured image is saved in a format that is suitable for digital decoding machines.

This new technology has brought about some positive strides in the world of medicine. The long messy job of chemical processing will not be done again. The resulting images can be transferred to other media and image enhancing software used to improve the quality. Unlike conventional imaging, this procedure will expose the patient to less radiation.

One kind of detector is made using amorphous selenium that captures the photons and converts them directly into charge. The charge pattern that is induced on the selenium layer is then read by electrometer probes or a micro plasma line addressing. Another variation of detectors has the outer layer made up of a combination of amorphous silicon and a scintillator.

The dentistry room will appreciate the abilities of the machines. By taking a shot of the ailing parts, the dentist can use the zoom feature on the screen display to get a closer look s well as for outlining the procedure to be performed to the patient. The image may be directed directly to a screen via USB connection or formed on phosphor plates for later recovery.

A typical machine for imaging in the hospital will have a main base station and a camera. The main base station houses and controls the radiation tube. It also works in conjunction with the camera to store pictures on a hard disk. This image is availed to an operator through an interface that allows him to analyze and enhance its quality.

The new Digital x ray system will usually require some programming for to realize its full potential. This will enable the automatic laser power control and warn of the end of life of the laser diodes. An observation about these new machines is their smaller size due to the miniaturization of components mounted on the board.
