| Research Abstract |
The purpose of this study is to develop a new position recognition system, which can detect the motion of the patient in real time without exposure of X ray in the Cyberknife treatment.
This system composed of three CCD cameras and the software for the detection of the patient position. This system could recognize the specific shapes of the nose and palpebral fissures, extract the edge lines of these structures, and detect the differences of the position of target and registered images using the feature matching. The experiment using a head phantom suggested that the accuracy of this system was similar to that of position recognition system of Cyberknife.
