Abstract: In one aspect, the invention relates to an ultrasound imaging system that includes an ultrasound receiver configured to receive ultrasound signals scattered from a sample in real time; an acoustic beam former; and an ultrasound data demodulation system. In one embodiment, the ultrasound imaging system further includes a processing system configured to process demodulated scan data and perform ultrasound image generation and flow processing and a display configured to show ultrasound image data and blood flow velocity data relative to such image data. Signals that include positive flow information and negative flow information are separated from received signals using phase-filters and analytic signal transforms such that a first and a second autocorrelation signal processing stage is used to generate mean positive flow, mean negative flow, and variance data for such flows.

Abstract: A system may include a touch screen device configurable to communicate with and control an ultrasound system. The system may further include an ultrasound user interface component configurable from the touch screen device, having one or more customizable properties, and representing an ultrasound system control component. At least one of the customizable properties of the ultrasound user interface component may be associated with a presence of the ultrasound user interface component on the touch screen device. The presence of the ultrasound user interface component on the touch screen device may be configurable via the touch screen device in response to receiving a user selection on the touch screen device.

Abstract: In one aspect the invention relates to a shear wave generator. The shear wave generator includes a first piezoelectric element having a first polarity in electrical communication with a first electrode; a second piezoelectric element having a second polarity in electrical communication with a second electrode, wherein the second polarity is an inverse of the first polarity; a boundary layer disposed behind both the first piezoelectric element and the second piezoelectric element; and an excitation signal generator in electrical communication with the first electrode and the second electrode, wherein the first piezoelectric element vibrates in a first direction and the second piezoelectric element vibrates in a second direction in response to an excitation signal. In one embodiment, the piezoelectric elements are disposed within an ultrasound imaging probe.

Abstract: An ultrasonic image scanning system for scanning an organic object includes a container for containing a coupling medium for transmitting an ultrasonic signal to the organic object disposed therein whereby a simultaneous multiple direction scanning process may be carried out without physically contacting the organic object. The ultrasonic image scanning system further includes ultrasound transducers for transmitting the ultrasonic signal to the organic object through the coupling medium without asserting an image deforming pressure to the organic object. These transducers distributed substantially around a two-dimensional perimeter of the container and substantially at symmetrical angular positions at approximately equal divisions of 360 degrees over a two-dimensional perimeter of the container. The transducers are further movable over a vertical direction alone sidewalls of the container for a real time three dimensional (3D) image data acquisition.

The ultrasonic image scanning system includes a switching mode power supply operated with a programmable clock in synchronization with the transmit carrier frequency. The switching mode power supply further provided with circuits for generating a low voltage and a high voltage. The ultrasonic image scanning system further includes transducers for projecting ultrasound signals wherein the transducers are connected to and electrically excited by the high voltage generated by the switching mode power supply.

Abstract: In one embodiment of the invention, there is an ultrasound processing system that communicates images over a single asynchronous serial channel according to a scheme that does not require an isochronous serial channel and that switches among ultrasound imaging modes robustly. For example, the system is configured to packetize ultrasound image data of at least one ultrasound imaging mode into a stream of data frames and to convey the stream of data frames via the asynchronous channel. Each data frame includes indication of the ultrasound imaging mode and includes ultrasound-imaging-mode-specific imaging parameters. Other embodiments exist.

Abstract: In part, the invention relates to an immersible ultrasound probe having a substantially cylindrical shape and a circular or elliptical cross-section. Typically, the circumference of the probe and the length of the cylinder define an inner surface upon which rows and/or columns of transducer are disposed. This surface can also be formed from panels or modules. The transducers can be formed in unitary substrate and electrical connected to a MEMs device and a multiplexer. The inner surface defines a cavity having at least one opening sized to receive a body object. The inner surface configured to receive acoustic signals while immersed in a fluid.
