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.
Computing time 3D/2D algorithm and cortical thickness take 2 minutes.
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.
Automatic mean cortical thickness:
Femoral neck band (medial, lateral, anterior, posterior).
Subtrochantic band (medial, lateral, anterior, posterior).
Trochanters band (medial, lateral, anterior, posterior).
