A hand-held ultrasound system includes integrated electronics within an ergonomic housing. The electronics includes control circuitry, beamforming and circuitry transducer drive circuitry. The electronics communicate with a host computer using an industry standard high speed serial bus. The ultrasonic imaging system is operable on a standard, commercially available, user computing device without specific hardware modifications, and is adapted to interface with an external application without modification to the ultrasonic imaging system to allow a user to gather ultrasonic data on a standard user computing device such as a PC, and employ the data so gathered via an independent external application without requiring a custom system, expensive hardware modifications, or system rebuilds. An integrated interface program allows such ultrasonic data to be invoked by a variety of such external applications having access to the integrated interface program via a standard, predetermined platform such as visual basic or c++.

Networked ultrasound system and method for imaging a medical procedure using an invasive probe

An ultrasonic imaging system produces a sequence of images of the heart during a cardiac cycle. The images are analyzed to determine the motion, displacement, or change in size of segments of the myocardium. In a preferred embodiment the values determined are radial, longitudinal, or circumferential myocardial strain values. The displacement of the myocardial segments may be tracked during the cardiac cycle by speckle tracking or border detection. The motion, displacement, or change in size values for the segments are analyzed to produce a recruitment curve and anatomical display showing the relative times of recruitment of the different segments in the contractile and relaxation motion of the heart. Participation in and achievement of full recruitment may be determined by comparison against an initial recruitment threshold criterion and against a predetermine maximal recruitment milestone level.

Ultrasonic assessment of cardiac synchronicity and viability

The present invention is directed to an ultrasound imaging system and method for Doppler processing of data. The ultrasonic imaging system efficiently addresses the data computational and processing needs of Doppler processing. Software executable sequences in accordance with a preferred embodiment of the present invention determines the phase shift and the auto-correlation phase of filtered image data. In a preferred embodiment, the system of ultrasonic imaging also includes a sequence of instructions for Doppler processing that provides the functions for demodulation, Gauss Match filtering, auto-correlation calculation, phase shift calculation, frame averaging, and scan conversion implemented with Single Instruction Multiple Data (SIMD) or Multiple Instruction Multiple Data (MIMD) instructions. In a preferred embodiment, the ultrasound imaging system of the present invention includes a processing module; and memory operable coupled to the processing module, wherein the memory stores operational instructions that cause the processing module to map serial data to vector representation, calculate an auto-correlation function of the data, calculate a phase shift of the auto-correlation function to generate a monotonic function covering all values of the phase shift corresponding to a range of Doppler velocities and display the resultant images, for example, as color images.
