In the Dynamic Imaging Lab we strive to generate novel techniques for Magnetic Resonance Imaging in the presence of motion, and to translate them from bench to bedside. There is a strong focus on the functions that display periodic motion (the cardiovascular system, joint kinematics), and aperiodic or irregular motion (neonatal/fetal imaging).
Current projects include 1) leveraging high-resolution 3D MRI in the field of electrophysiology; 2) using real-time low-latency image reconstruction for joint motion analysis; and 3) development of motion-compensation techniques for high-resolution imaging during breathing.
Our lab pursues advancement in all aspects of MRI — from gradient waveform design, to pulse sequence design, reconstruction algorithm development, and translation into clinic — and works directly with researcher physicians, and collaborates with industrial partners.
