摘要： 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.

摘要： 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.

摘要： 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 container further includes sidewalls covered with a baffle layer for reducing an acoustic reverberation.

摘要： An extended view ultrasound imaging system in which a position sensor is used to detect the location and orientation of a ultrasound transducer for each scan frame as the ultrasound transducer is swept across the surface of a target. The contents of the successive scan frames, together with their location and orientation information, are processed to generate an extended view ultrasound image of the target region. An output array representing the extended view image is first initialized, and then successively updated as each scan frame is received. In a preferred embodiment, an alpha-blending algorithm is used to combine the information in the current scan frame with previous output array values to generate the current output array values. Because the content of the successive image frames is not relied upon to piece them together, system processing requirements are substantially reduced and the output image is robust against increased transducer speed, bumps in the transducer path, and departures of the transducer from a common plane. In an additional preferred embodiment, the alpha-blending weighting factor can be user-adjustable and/or can be dynamically adjusted on a per-location basis based on acoustic reflectivity, edge motion, or other factors. Also in an additional preferred embodiment, the amount of departure from a common plane during the movement of the transducer across the target can be displayed to the user for assistance in interpreting the extended view image.
