Tunable Resonant Actuation for Magnetic Resonance Elastography of Active Tissues

Abstract

Intervertebral disc degeneration (IDD) is a common condition characterized by the deterioration of the discs separating the spine. Magnetic resonance elastography has shown potential in earlier diagnosis and investigation of DDD, but has been limited by available actuation techniques. This project aims to solve these actuation challenges by developing tunable resonance MRE actuators, establishing control methods for automated tuning and dual actuation, and combining these developments to characterize IVD stiffness in healthy human subjects. The project has been proceeding towards completion of each of the three aims, with development of tunable actuators, theoretical and practical advancements in self tuning capabilities and technology for IVD characterization in-vivo. The developed actuators demonstrated a nearly 500Hz resonance range, while positioning experiments validated the need for active tuning of actuator parameters
