Paper Abstract

In many surgical procedures, ultrasound is used for real- time visualization in order to minimize invasion of healthy tissue. Unfortunately, the exact location of soft tissues and the composition of tissues of interest may be difficult to determine using ultrasound. In interactive image guided surgery (IIGS), the display of present surgical position on preoperative tomographic imags enhances the surgeons locational awareness and provides knowledge of surgical anatomy. However, changes in the anatomy during surgery are not realized by the current IIGS techniques. This manuscript details initial experiments conducted to merge the strengths of intraoperative ultrasound imaging with IIGS. This includes: 1) developing a technique for accurately tracking an ultrasound probe in physical space and 2) determining a transformation to map ultrasound image space into physical space.
