We present a unified heat kernel smoothing framework for modeling 3D anatomical surface data extracted from medical images. Due to image acquisition and preprocessing noises, it is expected the medical imaging data is noisy. The surface data of the anatomical structures is regressed using the weighted linear combination of Laplace-Beltrami (LB) eigenfunctions to smooth out noisy data and perform statistical analysis.

Vowel Diagnostic Treatment in Down Syndrome
The Vocal Tract Development Lab at the Waisman Center, University of Wisconsin-Madison, needs participants with Down syndrome for a pilot research study. We have developed a diagnostic treatment study designed to improve vowel production in …

A bone to speak and to swallow
Only one out of the more than 200 bones in our bodies is free-floating, with no local attachment to other bones, but it’s no freeloader. The hyoid bone is located in the front of the neck, just below the lower jaw, carrying the weight of the tongue and playing a vital role in speech and swallowing.
