The N-VivoTM Hip BMD product is a new automated Application that utilizes CT 3-D volumetric images to provide Integral volumetric BMD and DXA like measurements of the hip. The CT images are calibrated using our calcium hydroxyapatite phantoms as with conventional QCT. Image processing methods for segmentations, calibration, coordinate system, rotations and ROI placements are all totally automatic. This is a first for bone densitometry. After segmenting the overlying soft tissue, the bone image data is re-projected from 3D to 2D space in the coordinate system. Similar ROIs and areal density results are produced as with conventional DXA. Physicians familiar with DXA can interpret our hip reports as they are accustomed and with similar diagnostic end points. WHO criteria for fracture risk are used and the patient results are compared to the NHANES reference data. Low bone density of the proximal femur is readily determined and can be compared to the clinical experience with DXA.
