    摘要： A digital transmit beamformer system with multiple beam transmit capability has a plurality of multi-channel transmitters, each channel with a source of sampled, complex-valued initial waveform information representative of the ultimate desired waveform to be applied to one or more corresponding transducer elements for each beam. Each multi-channel transmitter applies beamformation delays and apodization to each channel's respective initial waveform information digitally, digitally modulates the information by a carrier frequency, and interpolates the information to the DAC sample rate for conversion to an analog signal and application to the associated transducer element(s). The beamformer transmitters can be programmed per channel and per beam with carrier frequency, delay, apodization and calibration values. For pulsed wave operation, pulse waveform parameters can be specified to the beamformer transmitters on a per firing basis, without degrading the scan frame rate to non-useful diagnostic levels. Waveform parameters can be specified to the transmitters by an external central control system which is responsible for higher level flexibility, such as scan formats, focusing depths and fields of view. The transmit pulse delay specified per-channel to each transmitter is applied in at least two components: a focusing time delay component and a focusing phase component. The carrier frequency can be specified for each transmit beam, to any desired frequency within a substantially continuous predefined range of frequencies, and a beam-interleaved signal processing path permits operation in any of several predefined processing modes, which define different parameter sets in a trade-off among (1) the number of beams produced; (2) per-beam initial waveform sample interval; and (3) transmit frequency.

    摘要： A phased array sector scanning ultrasonic system includes a separate receive channel for each respective element in an ultrasonic transducer array. Each receive channel imparts a delay to the echo signal produced by each respective element. The delayed echo signals are summed to form a steered, dynamically focused and dynamically windowed receive beam even when the transmit beam does not emanate from the center of the array. The receiver has a beamformer including a multiplicity of beamformer channels. The beamformer dynamically increases delays to each channel without introducing unwanted discontinuities, by combining and synchronizing a FIFO and an interpolator. The interpolator uses "Wallace tree" adders to accumulate bit-shifted versions of the inputs. The number of additions is less than the number of bits which would be needed to represent equivalent coefficients. This reduces the hardware relative to a conventional implementation which incorporates multipliers with shifts and adds equaling the number of bits in the coefficients.

    摘要： An ultrasound imaging system enables 1.5D image information to be generated from a single firing of a linear transducer array by permitting dynamic control over the receive aperture. The imaging system comprises a transducer having a linear array of piezoelectric elements arranged in a plurality of distinct rows of the elements. The transducer is operable to provide acoustic pulses from elements of a first one of the rows in response to respective driving signals and to provide corresponding return signals in response thereto at elements of additional ones of the plurality of the rows and at the first one of the rows. A receiver is coupled to the transducer to receive a summed signal corresponding to the return signals from the elements. The receiver comprises a plurality of low voltage switches that couple to respective ones of the additional ones of the plurality of the rows, and a high voltage switch disposed in series with the low voltage switches. The timing of the high and low voltage switches is controlled to vary the focusing characteristics of the imaging system. A processor coupled to the receiver and the transducer generates a 1.5D image using the summed signal.
