Abstract: An ultrasound information processing system is disclosed in which ultrasound image data is packetized into ultrasound information packets and routed to one or more of a plurality of processors for performing image processing operations on the ultrasound image data, the ultrasound information packets being routed according to entries in a host-programmable routing table. A common distribution bus is coupled between packetizing circuitry and dedicated input buffers corresponding to each processor for distributing the ultrasound information packets, and a common output bus to is used to transfer processed image data from the processors to an output device. The disclosed ultrasound information processing system architecture allows for a high throughput rate for accommodating real-time image processing operations, while also allowing for ready programmability and upgradability. Advantageously, the disclosed ultrasound information processing system may be readily upgraded by coupling additional processors to the common distribution bus and the common output bus and by reprogramming the routing table to include the additional processors as destinations for the ultrasound information packets. The disclosed ultrasound information processing system architecture also provides for added field reliability by providing for an optional spare processor coupled to the common distribution bus and the common output bus, wherein upon detection of a failure of one of the existing processors, the optional spare processor may be loaded with a copy of a program being run by the failing processor and the routing table may by automatically modified to redirect ultrasound data packets from the failing processor to the spare processor.

Abstract: An ultrasound system that generates compound images from component frames having decorrelated speckle patterns. Successive sets of distinct, speckle-affecting parameters are used to generate successive component frames for compounding, and are selected such that the successive component frames have decorrelated speckle patterns. The speckle-affecting parameters that are changed from frame to frame may be selected from a wide variety of parameters, including transmit beamformer parameters, receive beamformer parameters, and demodulator parameters. According to a preferred embodiment, the successive sets of speckle-affecting parameters differ from each other by at least two speckle-affecting parameters. According to another preferred embodiment, the amount by which each of the multiple speckle-affecting parameters is changed is less than a decorrelation threshold for that parameter, that is, by less that the amount that speckle-affecting parameter alone would be required to change in order to yield decorrelated speckle patterns if no other parameters were changed. When more speckle-affecting parameters are changed, each speckle-affecting parameter can be changed by an amount less than its decorrelation threshold, and yet decorrelated speckle patterns can still be obtained. Moreover, because two different types of speckle-affecting parameters tend to alter the spatial resolution of the component frames in different ways, the spatial resolution of the compounded image can be better as compared to the scenario in which only one speckle-affecting parameter is altered by its decorrelation threshold.

Abstract: A demodulator for use in an ultrasound information processing system is described, where in a preferred embodiment the demodulator uses a half-band filter to perform mirror-cancellation during the demodulation process. The demodulator comprises a mirror canceling quadrature mixer that mixes the input signal with quarter-sampling-frequency sinusoids and then low-pass-filters the mixed signals with half-band filters having a cutoff frequency of one-fourth the sampling frequency. In an ultrasound demodulator in accordance with a preferred embodiment, a significantly sharper mirror cancellation on the wideband input signal is achieved. Additionally, the number and complexity of mirror canceling filter operations significantly reduced, allowing for easier hardware implementation using less expensive, off-the-shelf components. Furthermore, simplified hardware for digitally providing harmonic imaging applications is achieved.
