MRI-powered motors may allow the design of interventional medical robots that are powered, imaged, and control by MRI-scanners. Closed-loop control of an MRI-powered motor is necessary for maximum energy transfer and stability. This abstract presents a real-time tracking methodology based on RF-selective excitation that allows closed-loop control of an MRI-powered motor.
