It's now being tested in prostate biopsies. Doctors say this system will let them aim their needles more precisely and reduce the number of times they stick them in. The NIH thinks such systems could come in handy for neurosurgery too. Gregory Fischer, a professor of mechanical engineering at WPI whose Automation and Interventional Medicine Robotics Lab led the research says: "You can bring it into any MRI room and have it up and running in an hour. It can locate the target, track the needle, and if it deflects during insertion, it can steer the needle to hit the target. We’re taking baby steps to get the robot into clinical use."
