Abstract
An apparatus is provided for assisting breast biopsy. The apparatus includes a biopsy guide, a support system that effects three-dimensional movement of the biopsy guide and a system for registering coordinates of a remote center of motion (RCM) of the biopsy guide with a coordinate system on an image of a breast obtained from a parallel plate radiology imager. The biopsy guide has a mounting plate and a needle gun mount and ultrasound transducer mount on the mounting plate in a common plane. A biopsy needle of a needle gun mounted on the needle gun mount and an image plane of an ultrasound transducer mounted on the ultrasound transducer mount have longitudinal axes in or parallel to the common plane, which intersect at the RCM. The position of the RCM with respect to the biopsy guide is unchanged when the needle gun and/or ultrasound transducer moves on the biopsy guide.
