In this paper, the concept of ultrasound image-based force enhancement is introduced. It consists of a robotic comanipulation system that assists a surgeon performing an ultrasound exam through a minimally invasive access. The robot is programmed in such a way that the surgeon's feeling of the distal contact between the probe and the organ is enhanced,(More)
A novel robotic device, aimed at assisting a urologist in performing prostate biopsies guided by an endorectal ultrasound probe, is described. The paper describes the robot kinematics and the actuation system. The actuation system combines electromagnetic brakes, balancing springs, and electrical motors with cable transmissions. The robot supports two modes(More)
