Abstract: Methods, apparatus and systems for characterizing changes in at least one physical properly of soft tissue. A series of acoustic pulses is generated and directed into the soft tissue such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the tissue. Waves reflected off the tissue, or a flexible member that moves with the tissue, are received and measured to estimate at least one characteristic of the physical displacement induced thereby. Repetition of the generating, receiving and estimating steps provides characterization of the at least one physical property over time. Methods, apparatus and systems for characterizing at least one physical property or blood, by generating a series of acoustic pulses and directing the series of pulses into the blood such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the blood.
