Figure 2 Spine-based 2-D/3-D registration examples for electrophysiology[9]. A: Spine-enhanced fluoroscopy with the edge contours depicted; B: Digitally reconstructed radiographs (DRRs) before registration overlaid with the edge contours from fluoroscopy; C: DRRs after registration overlaid with the edge contours from fluoroscopy; D: 2-D/3-D overlay used for electrophysiology procedures. The 3-D mesh model is generated from the segmentation of the left atrium and pulmonary veins, and is overlaid with fluoroscopy by the proposed spine-based 2-D/3-D registration technique.
