Digital radiography refers to a type of X-ray imaging in which digital x ray sensors get made use of in place of conventional photographic film. When in need of digital radiography in dentistry Maui is the best place to check out. There are many dentists in Maui who specialize in using this technique in their practice in order to achieve better results. Many dentists are adopting this method because it is one of the latest technologies in the field of medicine.
In the place of x-ray films, digital radiography employs digital image capturing gadgets. The use of these image capture devices provide several advantage that make this method very preferable. For instance, this method offers immediate image availability and preview. When images are available immediately, they can be used in emergency procedures, something that could save lives.
Two main versions of digital image capturing gadgets exist, that is, high density line-scan solid state detector and flat panel detector. The term flat panel detector is abbreviated as FPD. FPDs are further classified as indirect FPDs and direct FPDs. Amorphous silicon, a-Si is used to make indirect FPDs. Commercial FPDs are commonly made using amorphous silicon, even though other kinds of materials may also be used.
The conversion of light from x-ray is done in indirect detectors when amorphous silicon detectors combine with scintillator created by gadolinium oxysulfide and/or caesium iodide. An output signal that is digital in nature is generated when light gets channeled through a photodiode layer. Computer screens can then be used to display the resultant output signal.
Direct FPDs are made of amorphous selenium, a-Se. They are known as direct detectors since x-ray photons get converted into charge directly. The photons produce pairs of electron/hole pairs the a-Se, which are then moved depending on the a cartage charge. The charge that is created can be read by electrometer probes, micro-plasma line addressing, active matrix arrays, or TFT array. The advantages of direct FPDs include time efficiency and the ability to transfer and enhance images digitally.
High-density line scan solid state detectors are constructed using photo-stimulable barium fluorobromide, which is doped with caesium bromide phosphor or europium. The detectors create images when x ray energy is recorded by phosphor during exposure. A laser diode then scans the phosphor to excite the energy it is storing, prompting it to be released. Once it is released, the energy is read by digital image capturing array found on a CCD.
This technology finds a lot of use in many industries, including aerospace and security. In the aerospace industry, this technology is used for the detection of defects in engine turbo disc, airframe structures, and blades. The technology is used during initial production of aeroplanes and during maintenance. This technology has helped to reduce aircraft crashes due to mechanical failure.
This technology has also been used in security industries for over twenty years now. It is used as a replacement for inspection x-rays in both security and NDT fields. This method is preferred in security because it presents many benefits over other methods. Some of the advantages it offers include high POD, excellent image quality, immediate imaging, environmental friendliness, and portability.
