In stereotactic radiosurgery we can irradiate a targeted volume precisely with a narrow high-energy x-ray beam, and thus the motion of a targeted area may cause side effects to normal organs. This paper describes our motion detection system with three USB cameras. The motion detection of a patient was performed by tracking his/her ears and nose with three USB cameras, where a pattern matching between a predefined template image for each view and acquired images were done with an active search algorithm. The results of preliminary experiments showed that the measurement accuracy of our system was less than 1.4 mm. We designed a new attachment for its clinical application and made a user interface for the stereotactic radiosurgery. © 2009 Springer-Verlag.
