Abstract :
We have developed a new device, that allows precise guided surgery through gamma-camera images in real time. It consists of a portable mini gamma camera combined with an image guided surgery system. We call this new instrument "Gamma Functional Navigator". The small gamma camera has been built by our group and has a spatial resolution of about 2 mm. The position of the gamma camera and the surgical instruments is determined by the navigator through infrared reflectors. A software program combines the images obtained by the gamma camera at different places to form at least a stereoscopic image of an organ. We have tested The Gamma Functional Navigator with different phantoms.
