MRI of larynx is a clinically relevant topic for assessment of tumor progression and evaluation of processes in human phonation. Dedicated 5 channel transmit/receive coil was proposed, simulated and designed to address the challenges of laryngeal MRI at 7 T. The coil was tested on volunteers and found out to exhibit an SNR advantage that allowed acquisition of images with sub-millimetre spatial resolution ( 0.25x0.25x0.2 mm3). We anticipate using this setup in further studies to gather reference data to be used in a finite-element model of phonation functions as well as in clinical research to study laryngeal tumors.
