"name": "The four experimental setups. The top left shows a setup for scanning the calibrated phantom in a water tank. A ring stand was used to secure the ultrasound transducer into a fixed position. The phantom may be moved at incremental distances away from the ultrasound transducer in the tank. The top right image shows the setup for scanning a limb with the standard gel approach. The ultrasound transducer is fixed to a ring stand facing toward the limb. A layer of ultrasonic coupling gel is placed between the transducer and limb surface. \nThe bottom left image shows a setup for scanning the limb in the water tank (so contact with the probe can be avoided. A ring stand is used to secure the ultrasound transducer. Distance between transducer and limb is held constant between each scan. Finally, the bottom right shows a setup with water tank + rotating probe (Ranger 2019), where a subject’s limb was scanned to collect 3D shear wave elastography data. The setup consists of a water tank with a ring bearing mounted on top. A custom 3D-printed mount secures the ultrasound transducer to the rotating portion of the ring bearing, thus allowing for circumferential rotation of the transducer around the limb at a fixed radius. Shear wave elastography imagery was collected at 10-degree increments around the limb in the longitudinal directions. The subject is situated above the tank and is asked to submerge their limb into the tank and place their foot flat on the bottom to minimize motion.",
