3D-DXA is a breakthrough technology that takes routine BMD images and reconstructs a 3D image of the femur. (The method had been validated by comparing the results of the reconstructed images with images taken with a CT scanner). This technology is only available on our Medix range for an optimal 3D analysis. With our Medix range you obtain information on bone density in g/cm² and g/cm³. Coupled with our 3D-DXA technology you also have access to the macro and micro structure, its cortical thickness and trabecular bone. How does it work? The algorithm uses a statistical model incorporating shape and density variations captured in a database of patients. This statistical model is subsequently registered onto the 2D DXA image, resulting in a 3D subject-specific reconstruction of the patient’s bone. From this 3D reconstruction can be automatically computed a set of 3D clinical parameters allowing for a better management of osteoporosis. Integrated to the Medilink range: Embedded in 3D-DXA box. Automatic. Computing time 3D/2D algorithm and cortical thickness take 2 minutes Potential For the first time, bone health experts have access to information about bone structure which was not possible before by using DXA images, especially volumetric information:​ vBMD (volumic BMD) trabecular, cortical and global (total femur, femoral neck, intertrochanteric, greater trochanter). Femoral Neck Axis Length in 3D. Femoral Neck Shaft Angle in 3D. Cortical thickness 3D distribution.
