Digital Imaging


The two types of digital imaging systems are Computed Radiography (CR) and Direct Radiography (DR). Golden Engineering X-ray generators are compatible with both. A CR system could be considered a digital film system. The film is replaced by an imaging plate that contains photo stimulable storage phosphors. After exposing the imaging plate to X-rays, it is placed in a special laser scanner, or CR reader, that scans and digitizes the image. Image processing time ranges from several seconds to less than a minute. After processing the image, the plate is erased by exposing it to light. CR Systems can be especially useful for X-raying larger objects where multiple image plates may be placed behind the object and exposed simultaneously. The individual images are stitched together to create the final image.

DR systems use a digital image capture device to record the image. The capture device can be a Flat Panel Detector (FPD) or combination Florescent Screen and CCD Camera. A cable or wireless option connects the image capture device to a computer or tablet where the image is viewed. Image processing time is only a few seconds. The operator controls the X-ray pulse setting and initiates X-ray pulses from the computer. DR Systems are especially beneficial for high volume applications that require quick processing time.
