Digital Imaging SystemThe GE digital image chain provides high-resolution digital imaging technology for general radiography. Digital image acquisition supports fast and efficient exam procedures, eliminating time spent handling film and cassettes, as well as reliability issues inherent in cassette tray systems, thus helping to reduce overall exam times and improve patient satisfaction.

Advanced Clinical ApplicationsThe non-tiled flat panel detector with high DQE, low noise and high detector acquisition speed allows the Discovery XR656 to offer the following advanced clinical applications:
VolumeRAD (optional):VolumeRAD is an advanced application in radiographic X-ray imaging, which allows the retrospective reconstruction of a number of planes (slices) from a series of ultra-low dose exposures acquired within a limited angular range. These slice images show anatomical structures at different depths within the patient.
VolumeRAD is a low dose diagnostic imaging technique that is superior to chest X-ray for lung nodule detection. VolumeRAD improves the ability of the radiologist to detect 3.6 times more small (3mm-20 mm) lung nodules in all diagnostically significant size ranges, without increasing the number of false positive findings†.
Compared to chest x-ray, VolumeRAD is more effective in supporting a radiologist to manage patient follow-up according to Fleischner Society guidelines†.
The average effective dose of a thoracic VolumeRAD tomosynthesis sweep is less than 0.1 mSv, 1.6 times more than a 2-view chest x-ray exam†.
VolumeRAD is available in various sweeps:
• Horizontalsweepofthetubeoverthetableforsupineimaging
• Verticaltubesweepatthewallstandforuprightimaging
• Horizontalsweepofthetubeoverastretcherforsupineimagingatthewallstand(requiresextendedarm)

The effectiveness of the device may vary depending on nodule prevalence and type.
