Abstract
This work presents a design framework and prototype for achieving high frequency mechanical motion that simulates the kinematics of human heart deformation. The proposed method begins with patient-specific, four-dimensional computed tomography imaging and proceeds to an actuator topology and control scheme that can be adapted to multiple uses. We present the overall simulation workflow and results from a prototype using four voice coil motors. The current prototype approximates left ventricular wall motion with a closed loop displacement bandwidth in excess of 30 Hz. This work is particularly relevant to medical device durability testing given its emphasis on high frequency motion.
