3D reconstruction of bone structures from DXA images (Ref.TEC0016)

Osteoporosis, which is characterized by low bone mass and microarchitectural deterioration, is a major risk factor for fractures of the hip, vertebrae, and distal forearm. Because occlusion between adjacent bones prevents the use of radiographic techniques to determine the internal structure of bones, an advanced imaging diagnostic test, such as CT scan, is required in order to obtain a representation of the internal structure of the bones.

This technology generates a 3D model of one or more bones in close contact with each other, e.g., the femur-hip joint, or the adjacent vertebrae and their internal structures. The technology requires a single radiographic DXA 2D image (a modality routinely used in clinics for osteoporosis diagnosis) in order to reconstruct the corresponding 3D bone model, thus reducing the need for more expensive and harmful imaging tests.

A patent covering the technology has been filed in Spain and a European Patent application is pending. The ownership is shared with CETIR Grup Medic.
