Paper Abstract

A three-dimensional ultrasound imaging system was developed for studying tongue configurations during speech and swallowing. A sequence of two-dimensional ultrasound B- mode images was acquired by moving the ultrasound transducer under the subject's chin. A six-degree-of-freedom electromagnetic position sensor was used in order to determine the spatial position and orientation of the ultrasound transducer during the scanning. Registration of image slices was achieved by using a time code generator to synchronize ultrasound images with the spatial information. Techniques were developed for 3D reconstruction of the tongue surface from multi-planar ultrasound scans using both commercial software and NIH- developed programs for PC and Macintosh computers. The system demonstrated its potential to quickly acquire and reconstruct 3D tongue images, and to assist speech pathologists and radiologists in speech and swallowing disorder diagnosis.
