Identification of muscle activity in tongue motion during swallowing through medical image data

Identification of muscle activity in tongue motion during swallowing through medical image data

This paper presents a formulation to identify muscle activities from the variation in shapes of organs during swallowing. We assume that each organ consists of a three-dimensional hyperelastic body, and the contraction movement of the muscle is caused by a contractive inelastic stress in the organ....
