PneuStep MRI robot for organ biopsies

Engineers at the Johns Hopkins Urology Robotics Lab are reporting the invention of a new MRI robot dubbed PneuStep that is intended to work within strong magnetic fields of the MRI machine and perform the MRI-guided organ biopsies. The new motor, which is without metal or electricity, can power robotic medical devices that are controlled remotely to be used for cancer biopsies and therapies The results are quicker and even more accurate as compared to that of human hand. The robot goes together with the patient in the MRI scanner and is controlled remotely by monitoring the images on the MR. It is claimed to increase precision in locating and gathering tissue samples, reduce diagnostic errors and also improve therapy.
