1. A method for producing orthopedic data using acoustic waveforms, comprising:
transmitting acoustic signals from a plurality of acoustic transducer elements in an array of an acoustic probe device toward a target volume of an orthopedic structure of a body part of a biological subject to which the acoustic probe device is in an affixed contact to limit movement between the body part and the acoustic probe device, wherein the orthopedic structure includes one or both of soft tissue and bone;
receiving acoustic echoes that return from at least part of the target volume at one or more of the acoustic transducer elements of the of the acoustic probe device while in the affixed contact, wherein the received acoustic echoes include at least some waveform components corresponding to the transmitted acoustic signals;
determining coordinate positions of the acoustic transducer elements of the acoustic probe device during the transmitting of the acoustic signals and the receiving of the acoustic echoes; and
processing the received acoustic echoes with the determined coordinate positions of the acoustic transducer elements to produce spatial information corresponding to returned acoustic echoes from the orthopedic structure, wherein the spatial information includes position data of the orthopedic structure and vector data of the orthopedic structure's movement derived from the determined coordinate positions of the acoustic transducer elements.
