Analysis of Tongue Dynamics from US

PhD Student: Lisa Tang
Principal Investigator: Ghassan Hamarneh

We are developing techniques for analyzing the movement of the human tongue as captured in 2D dynamic ultrasound.

  • Capable of automatic segmentation of over 500 frames in <4 minutes 
  • Method was validated on a set of 63 clinical data sequences
  • Experimental results demonstrate that our method can robustly segment US sequences containing over 500 frames with mean accuracy of 3 mm, using default parameters
