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.
