Abstract: An embodiment of wearable imaging system implements a set of sensors distributed around the joint of a user with advanced software machine learning techniques to deliver accurate measurements of bone-to-bone displacement and angle. A first subset of the distributed sensors emit ultrasound signals towards the joint of the user and a second subset detects ultrasound signals traveling through and reflected off structures of the joint. A controller of the wearable imaging system extracts physiological properties of the joint from the detected ultrasound signals. The controller inputs the physiological properties of the joint and properties of the detected ultrasound signals to a machine-learned displacement model to generate a bone displacement measurement at the joint.
