摘要： Architecture for driving an ultrasound phased array. The architecture includes a series of amplifiers (38) which produce discrete driving signals. The amplifiers number less than the number of transducer elements (32) in the array (31) and an integrated circuit multiplexer chip (34) is coupled to each transducer and to all the amplifiers. A controller (40) provides first control signals to the amplifiers (38) causing the amplifiers to produce their discrete driving signals. The controller (40) further provides second control signals to each multiplexer chip (34) and these signals cause the multiplexer chips to pass a specified one of the driving signals to a selected one of the transducer elements (32). The result is that a focused ultrasonic beam is formed on a selected target volume.

摘要： A multi-dimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.

摘要： An ultrasonic receive beamformer (10) includes transducers (11) forming receive signals that are applied to sub-array processors (12). Each sub-array processor includes at least one analog preconditioning circuit (13), phase shifter (14) and a summer (16), and each phase shifter is responsive to at least one of the transducer signals to shift the transducer signal by a respective phase angle and to apply the phase shifted transducer signals to the summer. Each of the summers supplies a summed sub-array signal via an analog-to-digital converter (18) to a respective beamformer processor (20). The phase angles for any one of the sub-array processors form a sum substantially equal to zero. Furthermore, the phase angles for any one of the sub-array processors are independent of the time delay of the respective digital beam former processor. The time resolution of the time delay of the digital beamformer processors is substantially as fine as the time resolution of the phase angles of the phase shifters. The phase angles of the phase shifters are updated at a slower rate than the focusing update rate of the beamformer processors.

摘要： A method and an apparatus are provided for dynamic, real time adaptive focussing (600) for ultrasound imaging. Aberration delay correction values, corresponding to an aberration region in an imaged subject, are measured (601) concurrently during B-mode imaging scan lines and updated at the scan line rate. The measured aberration delay correction values (Ek, L, Rk) are then applied concurrently (560) to correct the focus of all transmitted and received ultrasound scan lines, regardless of the imaging mode, scan geometry, or imaging frequencies.

摘要： A narrow-band phase shift beamformer system. The outputs from the elements in a transducer array are each divided into two components whose amplitudes are respectively proportional to the sine and cosine of the required phase shift, which are then processed so that the steered beam may be formed by coherent summation. The proportionalities of the respective sine and cosine components are achieved by switched capacitor circuits, which are preferably implemented by LSI circuits, permitting substantial hardware savings and yielding highly accurate component proportionalities.

摘要： A variable delay memory system (200) has an addressable memory means (66-1) having a data input port and a data output port. A counter (206) is connected to supply a write address on bus (212) for storage of data supplied to the data input port on bus (64-1). A subtracter means (214) is connected to receive the write address as means (214) is connected to receive the write address as one input on bus (210) and a second input proportional to a desired delay time on bus (72-1). The subtracter means (214) is connected to supply its output as a read address on bus (216) for data stored in the memory means (66-1) to be supplied at the data output port on bus (76-1). The variable delay memory system (200) is particularly adapted for use of its addressable memory means (66-1) as a delay line in an ultrasonic imaging system (50) with the second input proportional to a desired delay time being supplied by a correlator (70) on the basis of cross-correlations between the RF signals supplied on bus (64-1) and the RF signals supplied on corresponding buses (64-2) through (64-21) for other variable delay memory systems connected to the other channels of the ultrasonic imaging system (50).

摘要： The invention provides methods and systems for generating an ultrasound image. In a method, the generation of an ultrasound image comprises: obtaining channel data, the channel data defining a set of imaged points; for each imaged point: isolating the channel data; performing a spectral estimation on the isolated channel data; and selectively attenuating the spectral estimation channel data, thereby generating filtered channel data; and summing the filtered channel data, thereby forming a filtered ultrasound image. In some examples, the method comprises aperture extrapolation. The aperture extrapolation improves the lateral resolution of the ultrasound image. In other examples, the method comprises transmit extrapolation. The transmit extrapolation improves the contrast of the image. In addition, the transmit extrapolation improves the frame rate and reduces the motion artifacts in the ultrasound image. In further examples, the aperture and transmit extrapolations may be combined.
