摘要： A positioner for centering or otherwise situating medical devices such as biopsy needles with respect to a human body includes a clamp for receiving a portion of the human body (e.g., a breast), a carriage which moves along a carriage path next to the clamp, and a positioning arm pivotally mounted to the carriage and having a mount for a medical device thereon. The carriage may therefore carry the positioning arm along the carriage path to a desired location adjacent to the clamp, at which point the positioning arm may be pivoted to situate a medical device within the device mount at a desired location adjacent the portion of the body within the clamp. The components of the positioner are preferably made of materials that do not interfere with medical imaging instrumentation (e.g., MRI scanners), though the positioner may include markers at desired locations (e.g., on the positioning arm adjacent the device mount) which are visible by the imaging instrumentation so that the location of the medical device may be ascertained during imaging.
