Dynamic measurement of pennation angle of gastrocnemius muscles during contractions based on ultrasound imaging

<p>Abstract</p> <p>Background</p> <p>Muscle fascicle pennation angle (PA) is an important parameter related to musculoskeletal functions, and ultrasound imaging has been widely used for measuring PA, but manually and frame by frame in most cases. We have earlier reported an automatic method to estim...
