    Abstract: The present disclosure describes ultrasound systems and methods configured to determine stiffness levels of anisotropic tissue. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward anisotropic tissue having an angular orientation with respect to a nominal axial direction of the transducer. Systems can also include a beamformer configured to control the transducer to transmit a push pulse along a steering angle for generating a shear wave in the anisotropic tissue. The steering angle can be based on the angular orientation of the tissue. The transducer can also be controlled to transmit tracking pulses. Systems can also include a processor configured to store tracking line echo data generated from echo signals received at the transducer. In response to the echo data, the processor can detect motion within the tissue caused by propagation of the shear wave and measure the velocity of the shear wave.

    Abstract: An ultrasonic diagnostic imaging system produces contrast enhanced images which are processed differently during different stages of contrast agent wash-in. During an initial stage of contrast wash-in, imaging is done using pixels processed by maximum intensity detection, to better reflect the rapid change in contrast intensity. During a later stage of contrast wash-in, time averaged processing is used to diminish the effects of noise and motion on the pixel values. During an intermediate period of peak enhancement, a combination of both pixel values processed by both techniques is used. In another aspect, a wash-in period can be characterized by an appearance stage, a growth stage and a peak stage, in which contrast pixel data is adaptively processed in different ways during these periods.

    Abstract: Ultrasound systems and methods provide a workflow to automatically identify a fetal heartbeat. A region of interest (ROI) is identified in an ultrasound image and an ROI is identified that contains the fetal heart. The ultrasound system produces spatially different M-mode lines associated with the ROI. The ultrasound system can identify a fetal heartbeat by tracking the changing position of the heart wall and estimate the fetal heart rate, e.g. by measuring from peak-to-peak of two subsequent waves. The echo signals for the M-mode lines can also be ranked according to the likely presence of a fetal heartbeat in the echo data.

    Abstract: An ultrasonic diagnostic imaging system and method acquire a sequence of image data as a bolus of contrast agent washes into and out of the liver. The image data of contrast intensity is used to compute time-intensity curves of contrast flow for points in an ultrasound image. Time-dependent data is calculated from the data of the time-intensity curves which, in a described implementation, comprise first and second derivatives of the time-intensity curves. A color map is formed of the time-dependent data or the polarities of the data and displayed in a parametric image as a color overlay of a contrast image of the liver.
