Models of vocal fold biomechanics and vibration can be
used to study voice physics and to guide clinicians as
they attempt to restore or preserve voice quality in
persons with vocal or speech disorders. To assist in the
design of these accurate models we created a custom
2-channel phased-array receive-only coil for
high-resolution imaging of the larynx. T1 and T2
relaxometry was performed on an excised pig larynx to
understand the MR signal characteristics of various
tissues. These values were then used to choose optimal
sequence parameters for maximizing contrast between two
important tissues for modeling the larynx.
