Ultrasonographic Examination Of Tongue Movement During Articulation In Preschool Children, I-Chun Chen, Chien-Lun Peng

Rehabilitation Practice and Science

Ultrasound imaging provides a unique and complete representation of tongue structure in almost all planes of interest and is rapid enough to record real-time tongue movement during speech. Recording tongue movement with ultrasound is non-invasive, and has not been shown to have any biologic effects in humans at diagnostic intensities. As a result, ultrasound has been widely used in speech studies to measure tongue functions in recent years. However, these previous studies are subject to inconsistent plane images caused by additionally movement of the traditional handheld transducer. The artifacts that result from depression of the submental soft tissue contacted by …
