Real-Time Motion Correction for High-Resolution Imaging of the Larynx: Implementation and Initial Results

Jolle Karine Barral¹, Juan M. Santos¹, Dwight G. Nishimura¹

Respiratory motion is currently the main limitation to high-resolution MR imaging of the larynx. A novel algorithm integrating Compressed Sensing and the Diminishing Variance Algorithm is proposed and implemented within the framework of the real-time system RTHawk. The effectiveness of the approach is demonstrated on phantoms and in vivo.
