Endoscopy-MR Image Fusion for Image Guided Procedures

Endoscopy-MR Image Fusion for Image Guided Procedures

Minimally invasive endoscope based abdominal procedures provide potential advantages over conventional open surgery such as reduced trauma, shorter hospital stay, and quick recovery. One major limitation of using this technique is the narrow view of the endoscope and the lack of proper 3D context of...
