Abstract
A system (10) for conducting an image-guided medical procedure on a subject (20) includes a medical imaging apparatus (100) which intermittently during the procedure obtains, upon demand, real-time medical images of the actual procedure. A robotic arm (200) hold a medical instrument (e.g., a biopsy needle (210)) that is used to perform the procedure. The robotic arm (200) manipulates the medical instrument in response to drive signals from a haptic control (400). A detector (e.g., a strain gauge (230)) measures forces experienced by the medical instrument during the procedure. The haptic control (400) generates the drive signals in response to manipulations of an input device (e.g., a knob (404) or an auxiliary instrument, such as, in the case of a biopsy, a remote needle (500)) by an operator, and the operator receives tactile feedback from the haptic control (400) in accordance with the measured forces experienced by the medical instrument. A display (e.g., a video monitor (152)) shows a virtual planning view of the procedure. The virtual planning view depicts a pre-procedure image (310) of the subject (20) with a virtual medical instrument (e.g., a virtual needle (300)) correspo…
