SYSTEM AND METHOD FOR PERCUTANEOUS NEEDLE INSERTION
Inventors: Martin Wagner, Fred Lee, James Hinshaw, Giuseppe Toia, Meridith Kisting
UW-Madison researchers have developed a system and method for evaluating percutaneous needle pathways. Implemented in software, the system provides an automatic segmentation of local tissue structures and performs a weighting to rank a large number of paths to quickly identify clinically favorable choices. The system automatically evaluates a comprehensive range of needle paths for a given identified target, in some cases being over 50,000 different paths. This global evaluation is made possible by identifying and applying a set of anatomical rules and physician rules to weight each trajectory and provide a ranking of the best paths.
