3D DXA Software

Summary

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?

Content

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.

Content

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:​

Potential

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).
