摘要： Adaptive grating lobe suppression is provided. Received ultrasound data is measured, compared or otherwise processed to determine the presence of grating lobe energy. A further process is then altered as a function of the level of grating lobe energy. In one embodiment, the adaptive grating lobe suppression is implemented in the receive beamformer. Data representing a virtual element is formed as a normalized sum of data from adjacent sparse elements. The data from the adjacent elements is correlated to determine the presence of grating lobe energy as a function of the amount of shift associated with the peak correlation. A phase shift is applied to the data representing the virtual element where sufficient grating lobe energy is determined. In another embodiment, an amount of grating lobe energy is measured by comparing data from prior to a filter with filtered data. The filter is selected to isolate main lobe energy from grating lobe energy. A gain is modulated as a function of any detected grating lobe energy or filtered or unfiltered data is selected for further processing.

摘要： The present invention includes a fully programmable plurality of multi-channel receivers, each receiver having a digital multi-channel receive processor and a local processor control. Each receive processor includes a first decimator, time delay memory, second decimator, and complex multiplier. The receive beamformer is a computationally efficient system which is programmable to allow processing mode trade-offs among receive frequency, receive spatial range resolution, and number of simultaneous beams received. Each local control receives focusing data from a central control computer and provides final calculation of per-channel dynamic focus delay, phase, apodization, and calibration values for each receiver signal sample. Further, this invention includes a baseband multi-beam processor which has a phase aligner and a baseband filter for making post-beamformation coherent phase adjustments and signal shaping, respectively. The phase aligner maintains scan-line-to-scan-line coherency, such as would be required for coherent image formation. Accordingly, the present system can operate under multiple imaging formats, using a variety of transducers and a variety of modes such as B-mode, M-mode, and color Doppler flow mode.

摘要： This invention presents a multi-beam baseband processor for making post-beamformation adjustments to the complex (in-phase/quadrature) pre-detection scan line samples acquired from a receive beamformer of an ultrasound imaging system. Specifically, the invention includes a programmable finite impulse response (FIR) filter and a programmable complex multiplier. The programmable filter performs signal shaping and sample-rate conversion. The signal shaping capability may be used to compensate for transducer and analog signal path responses, to increase signal-to-noise ratio (SNR) by rejecting out-of-band noise frequencies, to operate as a matched filter to the transmitted waveform shape, and to act as both a smoothing and anti-aliasing filter during rate-conversion operation. The programmable multiplier permits both amplitude and phase adjustments of the complex data that assures amplitude and phase coherency between acquired scan lines, compensating for the effects of a selected scan format or the differences in ultrasound frequencies used to produce each scan line.

摘要： A method and apparatus are provided for imaging an object using a transducer array for transmitting one or more beams that are steered and/or translated to transmit scan lines for multiple excitation events so as to scan a field of view of the object, for sensing received signals reflected from the object after each excitation event on one or more receive beams on receive scan lines, and for transducing those sensed received signals into corresponding electrical signals. The method and apparatus is additionally for acquiring and storing coherent samples retaining both phase and amplitude information of those electrical signals obtained on the receive scan lines throughout at least a portion of the field of view, and for combining stored coherent samples associated with distinct receive beams to synthesize new coherent image samples aligned on synthetic scan lines which are distinct from any one of (1) receive scan lines on which a signal was sensed, (2) transmit scan lines on which a signal was directed, or (3) transmit scan lines and receive scan lines. The method and apparatus is further for detecting the synthesized coherent image samples and displaying or recording the resulting image field.

摘要： A beamformer control system includes a primary control and secondary controls so that delay and apodization beamformation profiles can be generated on a dynamic and distributed basis with sparsely sampled base delay and apodization data sets first expanded to the final values by the primary control and then further expanded in the secondary controls associated with multi-processing channels of the beamformer systems. The beamformer control system coordinates the transmit and receive beamformer systems preferably using data sets common to all beamformer systems, and by advantageously specifying to all beamformer systems, processing mode trade-offs among the signal nominal center frequency, the range spatial resolution, and the number of beams. The beamformer control system supports multiple simultaneous beam operation, as well as beam-to-beam adjustable frequency and synthetic aperture operations. Further, the present beamformer control system maintains beam-to-beam coherent receive beamformation and supports adaptive beamformation.
