Fig. 1: Overview of the A-mode ultrasound system.

A Exploded view of the wearable transducer mount. Four SETs are mounted on a 3D-printed case and attached to the body using a compressive fabric band. B Photograph of SETs worn on the upper arm over the BB muscle belly. C Photograph of SETs worn on the upper leg over the RF muscle belly. D Representative A-mode ultrasound data during concentric contractions of the parallel BB muscle (top) and the pennate RF muscle (bottom). Red dashed lines indicate superficial and deep muscle boundaries measured with the MBTA. Right insets show representative raw ultrasound data at specific time frames.
