The miniaturization of ultrasound technology provides an opportunity to utilize imaging in new point-of-care settings. The goal of this study was to investigate the feasibility of a universal serial bus (USB) based ultrasound transducer for dynamic imaging of the muscle function during gait. Axial strain of the rectus femoris muscle was measured during gait using the portable USB probe and compared...
We have developed an office based vector tissue Doppler imaging (vTDI) that can be used to quantitatively measure muscle kinematics using ultrasound. The goal of this preliminary study was to investigate if vTDI measures are repeatable and can be used robustly to measure and understand the kinematics of the rectus femoris muscle during a drop jump task. Data were collected from 8 healthy volunteers...
