摘要： A method and apparatus for detecting cardiac events. Ultrasonic data comprising a heart cycle is acquired by a probe. Tissue velocities associated with the ultrasonic data are detected. One of a maximum and a minimum value is detected based on the tissue velocities. A time within the heart cycle associated with the maximum or minimum value is determined, and a cardiac event is detected with respect to the time within the heart cycle and the maximum or minimum value.

摘要： A method and an apparatus for imaging blood motion by displaying an enhanced image of the fluctuating speckle pattern. A continuous stream of data frames, each the result of one scan, is available for processing. For each position in the scan plane, a respective time sequence of signal samples is available for processing. The first step in the blood motion image processing is high-pass filtering of this signal. Following the high-pass filter, a speckle signal is formed, e.g., by calculating the squared magnitude (i.e., power) of the high-pass-filtered signal (I/Q or RF). The resulting speckle signal can then undergo a nonlinear amplitude transformation to form a blood motion imaging signal for display.
