Abstract

Disclosed is a system and method for registering images from two medical imaging modalities in a six-degree-of-freedom coordinate space, for the purpose of providing real time registered imagery for optimization of medical procedures. The system and method uses fiducial that is visible to the first imager and in a fixed position and orientation relative to the second imager. The first imager may be an X-ray device such as a C-arm fluoroscope, and the second imager may be a Transrectal Ultrasound (TRUS) device.
