Guiding instruments with image software.

Columbia-Presbyterian Medical Center, New York City, has installed a new neurosurgical operating system, a blend of virtual and real surgery that greatly advances preoperative planning and increases the safety and precision of operations. The SurgiScope system consists of advanced image-handling software, a position sensor system, and a robotic microscope holder, which can accommodate lasers, endoscopes, and other instruments. Together, this equipment provides visual feedback to the neurosurgeon regarding the position of the operating instruments in relation to the patient's anatomy. The images, which can be viewed in 3D from various angles, are updated continuously during the procedure, helping the doctor visualize and navigate to a selacted target within the brain.

"With the SurgiScope, we can directly integrate information from various imaging studies into a surgical procedure," explains Robert Solomon, chairman of neurosurgery. The system works with images from MRI and CT scans, as well as digital and MR angiography. The system also helps with preoperative planning. The location of the target point or volume, optimal trajectory, and placement of the craniotomy can be decided prior to surgery, while alternative approaches and...
