Abstract: The present invention relates to systems and methods for signal processing of an ultrasound images. More specifically, a preferred embodiment of an ultrasound imaging system includes a transducer array that provides imaging signals at a first frequency, f1, and at a second frequency, f2, into a region of interest. A beamforming system processes image data at a third frequency that is a function of the first frequency, f1, and at the second frequency, f2. The processing system processes the ultrasound image using the function of the first frequency, f1, and the second frequency, f2. The function of the third frequency is a non-linearly-generated, higher-order, mixing term, f1+f2.

Abstract: A system and method for real-time quantitative analysis of heart wall motion is provided. A Doppler imaging system is used to monitor the movement of a heart, or other organ. A B-mode reference image of the target organ is made and then a region-of-interest is defined through the use of a gate. Then pulsed wave spectral tissue Doppler data of the region-of-interest is formed and used to determine the velocity of a region of the target organ. The system may be used for determining appropriate biventricular pacemaker settings for patients suffering from heart disease.

Abstract: A multi-dimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can be include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.
