Abstract
A computer controlled system for guiding the needle device, such as a biopsy needle, by reference to a single mode medical imaging system employing any one of computed tomography imaging (CTI) equipment, magnetic resonance imaging equipment (MRI), fluoroscopic imaging equipment, or 3D ultrasound system, or alternatively, by reference to a multi-modal imaging system, which includes any combination of the aforementioned systems. The 3D ultrasound system includes a combination of an ultrasound probe and both passive and active infrared tracking systems so that the combined system enables a real time image display of the entire region of interest without probe movement.
