摘要： A weight value used for a beamforming process performed on received signals in an ultrasound imaging apparatus is obtained with a small amount of computations and with a high degree of precision, even when a method of adaptive signal processing is employed. Multiple elements 401 receive ultrasound signals from a test subject, and the similarity operator 404 obtains the similarity between the received signals x(n). By using the similarity C(n) between the received signals obtained by the similarity operator 404, the adaptive weight operator 407 computes the adaptive weight w(n) in association with the similarity. The beamforming operator 408 uses the adaptive weight w(n) and the received signal x(n) to generate a beamforming output. The imaging processor 108 uses the beamforming output to generate image data. By way of example, the similarity operator 404 performs computations of the similarity in the time direction.

摘要： A beamforming method according to the present invention is a method of processing echo signals of a target region which are obtained from a probe including a plurality of receiving elements arrayed on a predetermined line. The beamforming method includes the following steps (S1 to S3). At S1, seed beams are formed from echo signals received by at least two receiving elements from among the plurality of receiving elements. At S2, a main beam and sub beams are formed by synthesizing at least one of the seed beams. At S3, a narrow beam for the target region is formed by multiplying the sub beams by respective predetermined coefficients and subtracting the multiplied sub beams from the main beam. Here, an signal intensity for the target region regarding the main beam is higher than a signal intensity for the target region regarding each of the sub beams

摘要： A device images time-wise in parallel using transducer elements of a group. The elements are of a current group and imaging is time-wise sequential by group. The groups may be spatially disposed with respect to each other so as to mutually intermesh element-wise. The imaging may include volumetric imaging. The device may be configured for not collectively using any of the elements to focus, nor to steer, a beam used in the imaging. The device may further be operable to transition between spacing states at least one of which is characterized by a respective minimum, nonzero, degree of intra-group, element-to-element non-adjacency, or may be fixed at a selected spacing state. The transitioning may be automatic, in response to input indicative of blood vessel size and/or depth.

摘要： A method and related system for improving resolution and frame rate of ultrasound images that includes specifying individual element transmit characteristics for each transmit beam in a set of transmit beams; determining various attributes of the transmit beams at field points in the field of view; using one or more of the attributes to determine if received ultrasound echo signals contributed by each transmit beam are qualified for use in image formation, and if so, how the signal should be processed; storing the determined information for each field point for repeated use with each new image frame; using the stored information to select and process subsequent received echo signals for each field point to produce an image parameter at the field point for each qualified echo signal; and combining multiple image parameters from overlapping transmit beams for a field point to produce a final image parameter that constitutes the field point value for the image frame.

摘要： Even when electroacoustic conversion elements with high nonlinearity are employed, a nonlinear imaging is carried out with extracting more nonlinear components. An ultrasonic wave beam is transmitted twice from the transmitter to an identical position on the imaging target, and the signal processor performs computation on the reception signals obtained in every transmission performed twice, thereby extracting a nonlinear component included in the reception signals. In one transmission out of the transmission performed twice, the transmitter delivers the transmission signal to all of multiple electroacoustic conversion elements for driving the electroacoustic conversion elements, and in the other transmission, the transmission signal is delivered selectively only to a part of the multiple electroacoustic conversion elements for driving the electroacoustic conversion elements.

摘要： High-frequency ultrasound imaging can be performed with greater quality and suppressed grating lobes by using methods and systems for effectively reducing the temporal length of transmit grating lobe signals in received ultrasound echoes. Systems and methods are provided for improved high-frequency ultrasound imaging. In various aspects, the method of shortening the time domain of grating lobe signals comprises splitting an array of N transmit elements into K sub-apertures. In further aspects, the grating lobes are suppressed by performing signal processing of the shortened grating lobe signals. In certain aspects, the signal processing method comprises weighting the samples by a calculated phase coherence factor.
