Validation of HD FoV Scans with a Gammex tissue characterization phantom show HU accuracy of up to +/-20 HU and a skin line accuracy of up to +/- 2 mm up to the bore size1,2,3 1. The image quality for the area outside the 50 cm standard scan field of view does not meet the image quality of the area inside the 50 cm standard scan field of view. Image artefacts may appear, depending on the patient setup and anatomy scanned. 2. As demonstrated in phantom measurements employing the Gammex 467 phantom; clinical results may vary.

Results from validation can only be reproduced with a Gammex 467 phantom position, that equals the positioning used in the white paper. A modified test set up can lead to different results.

DirectDensity™ reconstruction is not intended to be used for diagnostic imaging. As shown by measurements with a Gammex 467 Tissue Characterization Phantom comparing standard reconstruction (kernel Qr40) and DirectDensity™ reconstruction (kernel Sd40/Sm40). Image value to relative electron/mass density conversion for the standard reconstruction was based on a two- linear-equations approach with individual calibration for each tube voltage. For DirectDensity™ images, a single tube-voltage-independent linear conversion was used.
