    Abstract: A method of acquiring ultrasound images for a rheumatoid arthritis examination comprises receiving a hand in a scanning assembly including a transducer array and a fluid providing an acoustic coupling between the transducer array and the hand and identifying locations of a plurality of finger joints of the hand while the hand is held stationary in the scanning assembly. Ultrasound images of the plurality of finger joints are acquired with the transducer array while the hand is held stationary in the scanning assembly, wherein the ultrasound images are of an area less than an entire area of the hand based on the identified locations of the finger joints of the hand.

    Abstract: In accordance with embodiments disclosed herein, systems, methods, and computer programs are provided that determine a mechanical property of a subject. An excitation force is applied to a displacement origin within a subject, and a shear wave is generated in response to application of the excitation force. The displacement data indicative of displacement motion at the sample position is sampled by tracking pulses, and the timing of at least one of the tracking pulses is adjusted relative to application of the excitation force. The process continues until a peak displacement of the shear wave for the sample position is determined based upon the displacement data.
