From: 2D-3D Registration of CT Vertebra Volume to Fluoroscopy Projection: A Calibration Model Assessment

Figure 1

General sketch of the proposed method. A 3D CT vertebra model is available (the vertebra's 3D rendering is shown at centre). A DRR can be reconstructed from any orientation and distance. DRRs can be matched with a real DVF radiographic projection using a similarity index. The DRR that maximises the similarity with the real image is searched for. This procedure provides the vertebral 3D pose estimation.
