Abstract
Obtaining accurate force and kinesthetic information produced by actuators is necessary for the success of robot-assistive surgical operations. Access to such information is not readily possible in MR environments due to the effects of giant static and gradient magnetic fields. The goal of this study is to quantify the effects of MRI on the behavior of ultrasonic motors (USMs), while performing bone biopsies on pediatric surgery. In this study, the effects of three sequences (FFE, balanced FFE, and ultra-fast spin echo, SSH- TSE) were considered on the torque generated by a USM, transferred as an axial force by our implemented robot and measured by our developed force feedback system. Different sequences show different effects on the generated axial force while the motor rotates in different directions
