Digital Imaging

Computed Radiography (CR) uses equipment very similar to conventional film radiography except that in place of a film to create the image, an imaging plate (IP) made of photostimulable phosphor is used. The imaging plate is housed in a special cassette and placed in the table or wall bucky or under the object or body part to be examined and the x-ray exposure is made.
So, instead of taking an exposed film into a darkroom for developing in chemical tanks or an automatic film processor, the imaging plate is run through a special laser scanner, or CR reader, that reads and digitizes the image. The digital image can then be viewed and enhanced using software that has functions very similar to other conventional digital image-processing software, such as contrast, brightness, filtration and zoom.

Digital Radiography (DR) The most common material used in the manufacturing of flat panel detectors (FPD) is Amorphous silicon (a-Si). Combining a-Si detectors with a scintillator in the detector’s outer layer, which is made from caesium iodide (CsI) or gadolinium oxysulfide (Gd2O2S), converts X-rays to light. The digital signal is then read out by thin film transistors (TFTs) or fiber-coupled CCDs. The image data file is sent to a computer for viewing by digital image-processing software.
Initially CR was the system of choice; early DR systems were prohibitively expensive except for large clinics and hospitals.

We realize at Volunteer X-ray that one size does NOT always fit all. We tailor your Computed Radiography or Digital Radiography solution and full product lifecycle support requirements to your specific needs. We have numerous options available from several manufacturers to find the system that fits your needs and your wallet. Whether you want new, used or a combination of both, we will always strive to provide you with the right diagnostic equipment, from room design to installation and after-the-sale service.
