摘要: An ultrasonic diagnostic imaging system produces an image of shear wave velocities by transmitting push pulses to generate shear waves. A plurality of tracking lines are transmitted and echoes received by a focusing beamformer adjacent to the location of the push pulses. The tracking lines are sampled in a time-interleaved manner. The echo data acquired along each tracking line is processed to determine the time of peak tissue displacement caused by the shear waves at points along the tracking line, and the times of peaks at adjacent tracking lines compared to compute a local shear wave velocity. The resultant map of shear wave velocity values is color-coded and displayed over an anatomical image of the region of interest.

摘要: An ultrasonic diagnostic imaging system and method are described by which a fundamental frequency signal is transmitted into the body and harmonic (nonlinear) echo returns are received from the transmission. The harmonic echo signals are Doppler processed and displayed. The harmonic Doppler signals may be displayed alone, or in combination with a fundamental frequency or harmonic grayscale image. In a preferred embodiment harmonic signals returned from moving tissue are segmented on an intensity or frequency basis and displayed. The inventive apparatus and method provide highly resolved ultrasonic images of moving tissue which are substantially unobscured by image clutter from structures or tissue in the near field.

摘要: An ultrasonic imaging system is provided which produces signals representative of tissue motion through amplitude detection of echo signals from which stationary clutter has been removed. Tissue motion may be distinguished from noise and flow signals on the basis of the dynamic range of the detected signals. The tissue motion signals may be displayed in combination with B mode signals to augment images of moving tissue, or in a two dimensional image in combination with B mode and Doppler image information. A sequence of gated tissue motion images of the heart may be displayed with each image of a different phase of the heart cycle displayed in a different color. The sequence may be played in a real time sequence, or the images accumulated in a common static image which overlay and hence mask one another, thereby revealing subtle differences in motion from one phase of the heart cycle to another.
