PLX8200 is a very popular product in the world market. It is digital radiography sytem with CCD detector.
Digital radiography is a form of X-ray imaging, where
Compared with traditional x-ray film, digital radiography uses a digital image capture device. The gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display of the image.
There are two major variants of digital image capture devices: flat panel detectors and CCD detectors.
The phosphor detector records the X-ray energy during exposure and is scanned by a laser diode to excite the stored energy which is released and read out by a digital image capture array of a CCD.
The radiological examinations in dentistry may be classified into intraoral and extraoral. Extraoral imaging is further divided into orthopantomogram, showing a section, curved following more or less mandible shape, of the whole block and cephalometric analysis showing a projection, as parallel as possible, of the whole skull.
Digital radiography provides the clinician with the ability to store their images on a computer. This provides two key advantages over film in the form of full screen images that can be enhanced and zoomed in on, as well as allowing dental offices to communicate images electronically, allowing for simpler referrals and, where applicable, easier insurance claim submission.
Aerospace is an industry that has experienced great growth in recent decades. aerospace has a special driver of its own due to the high levels of human traffic involved; the crash of a civil or military airliner has the ability to cause loss of life reaching catastrophic proportions. Therefore, strict specifications have been set to detect very small cracks and defects in engine turbo discs, blades and airframe structures, in both production and ongoing maintenance.
Digital Radiography has existed in various forms in the security X-ray inspection field for over 20 years and is rapidly replacing the use of film for inspection X-rays in the Security fields. DR has opened a window of opportunity for the aerospace industry due to several key advantages including excellent image quality, portability, environmental friendliness and immediate imaging.
Digital dental radiography comes in two forms: direct and indirect. Direct digital sensors represent a significant initial investment, but in addition to the convenience of digital images, provide instant images that can reduce the time the patient spends in the dental chair. They also reduce the need for the constant purchase of film and the necessary development chemicals..
Indirect digital imaging is different with direct one, which uses a reusable plate in place of the film. After X-ray exposure the plate is placed in a special scanner where the latent formed image is retrieved point by point and digitized, using laser light scanning. The digitized images are stored and displayed on the computer screen. This method is halfway between old film-based technology and current direct digital imaging technology. It is similar to the film process because it involves the same image support handling but differs in that the chemical development process is replaced by scanning. This is not much faster than film processing and the resolution and sensitivity performances are contested. PSP has been described as having an advantage of fitting within any pre-existing equipment without modification because it replaces the existing film; however, it includes extra costs for the scanner and replacement of scratched plates.
Now the CCD detector technology on radiography system has been very mature, and the price for this kind of DR has also been lowered. So it becomes more andmore popular in some not so rich countires, such as in Latin America and Afriaca.
