Automatic Localization of Vertebral Levels in X-Ray Fluoroscopy
Using 3D-2D Registration: A Tool to Reduce Wrong-Site Surgery
Y. Otake et al.

A paper in the Physics in Medicine and Biology Journal shows a new method to automatically identify vertebrae in x-ray fluoroscopy. Such techniques could offer a valuable assistant to avoid a major source of wrong-site surgery. As an aid to the surgeon in localizing vertebrae during surgery, the 3D-2D registration method (called “LevelCheck”) registers any information defined in preoperative CT directly on the fluoroscopic view – for example, spine labels and desired trajectories of surgical tools. The method employs fast forward projection methods implemented on GPU for near-real-time computation of DRRs. Initial implementation demonstrates a high degree of accuracy (>99%) and robustness to anatomical change.(See Otake et al. Phys. Med. Biol. 2012, below)
