3d-Shaper - Dual-Energy X-ray Absorptiometry (DXA) Scan Software
3D-SHAPER analyzes the proximal femur in 3D from a standard 2D Dual-energy X-ray absorptiometry (DXA) scan. It provides clinicians with a separate assessment of trabecular and cortical bone.

Technology
DXA is the gold standard technique used for the management and follow-up of osteoporosis. 3D-SHAPER is a software application that registers a 3D statistical model onto the hip DXA scan of the patient, and uses a model-based algorithm to create a 3D map of the cortical surface density. It allows clinicians to assess the cortical and trabecular macrostructure in 3D from a standard hip DXA scan.
Validation
A multicenter clinical study was performed to compare 3D-SHAPER with Quantitative Computed Tomography (QCT) analyses. Strong correlations were found between measurements performed using the two techniques [1].
