    Abstract: The present invention discloses a novel technique that combines Diverging Beam with Synthetic Aperture Technique (DB-SAT). This technique aims at reducing the system's complexity (only 8 or 16 active transmit 10 elements) without compromising the image quality, and yet yield frame rates comparable to or higher than that obtained from Conventional Focused Beamforming with Linear Array (CFB-LA).

    Abstract: A system for detecting blood velocity within a blood vessel includes a transducer array including a plurality of transducers. Each of the transducers includes a carrier substrate; at least one spacer extending upwardly from substrate, a transducer element attached to spacer such that the piezoelectric transducer is spaced apart from the substrate, and setting electrodes positioned on the upper surface of the substrate under the piezoelectric transducer. A tilt control system is configured to apply a bias voltage to the setting electrodes which causes the transducer element to pivot about a pivot axis between a first tilted position and a second tilted position.

    Abstract: An ultrasound system drives the elements of an ultrasound probe with asymmetric transmit signals which reinforce poling of the probe transducer. The use of asymmetric transmit signals enables a transducer element to withstand a significantly higher RF transmit voltage without degradation, which in turn enables higher acoustic output and improved reliability. This is particularly beneficial with single crystal transducer material when used to generate high energy pressure waves of long duration such as shear wave push pulses.

    Abstract: An ultrasound system is described which produces blended fundamental and harmonic frequency images. Successively transmitted, differently modulated pulses are transmitted by an ultrasound probe and both fundamental and harmonic frequencies are received in response. The echo signals received from the two pulses are processed by pulse inversion, producing cleanly separated bands of fundamental and harmonic signals in which undesired components have been cancelled. Since the two bands have been separated by signal cancellation rather than filtering, the two bands are allowed to overlap, providing broadband signals in each band. The bands are filtered by bandpass filtering to define the fundamental and harmonic signals to be imaged. The signals are detected, and the detected signals are combined after weighting to produce a blended fundamental/harmonic image.
