摘要： A method for ultrasound imaging of anatomical tissue. A first signal is received from a first imaging ultrasound wave which has been reflected from a location in the anatomical tissue during a first time period (16). A second signal is received from a second imaging ultrasound wave which has been reflected from the location in the anatomical tissue during a later second time period (20), following a discrete medical treatment (14). The second signal is subtracted from the first signal to form a difference signal (22). The difference signal may be scaled, spatially filtered, then used to generate an indication, the indication showing the effect of the medical treatment in the location in the anatomical tissue.

摘要： A method for measuring the temperature rise in anatomical tissue as a result of ultrasound treatment. A first ultrasound signal is obtained (14) prior to treating the anatomical tissue, then a second ultrasound signal is obtained (18) after the tissue is treated. Complex analytic signals are computed (30) from the first and second ultrasound signals, then the depth-dependent delay is computed (32) from the complex analytic signals. An echo strain map is generated (34) from the slope of the depth-dependent delay. The echo strain map is used to estimate the amount of temperature rise from the first ultrasound signal to the second ultrasound signal (38). An image may then be created (22) showing where temperature rise is occurring in the anatomical tissue.
