Abstract
This paper used tagged-MRI and cine-MRI images, collected with the same parameters, to study whether Deformable Registration (DR) could be used to track tissue points within the tongue from cine-MR images. Ten subjects repeated the words "a geese" multiple times while sagittal images of the head were collected at 26 Hz, first in a tagged-MRI data set, and then in a cine-MRI data set. Harmonic Phase Imaging (HARP) tracked the motion of eight specified tissue points in the tagged data set. HARP is considered the gold standard for tracking tissue point motion in tagged MRI data. DR tracked the same eight points in the cine MRI dataset. Length changes were calculated for several muscles using the DR and HARP tracked points. Results showed that the DR point tracks and muscle lengths had many similarities to the HARP data. However, the errors were non-systematic, making corrections impossible.
