New Guidance System for Minimally Invasive Surgery

Researchers at Johns Hopkins have published a report in the journal Physics in Medicine and Biology that reports on their new image-based guidance system, which they say tests show is potentially superior to conventional surgical navigation tracking systems.

The team started with a mathematical algorithm they had previously developed to help surgeons locate specific vertebrae during spine surgery, and adapted it to the task of surgical navigation using a mobile C-arm for an alternative to the current manual registration process. The system matches two-dimensional X-ray images to the three-dimensional preoperative CT scan in a way that is automatic and remains up to date throughout the operation.
