摘要： An ultrasonic imaging method and apparatus wherein the ultrasonic energy transmitted to a subject under examination is generated by a plurality of electroacoustic transducers, which are actuated for transmission with predetermined delays according to a predetermined focusing rule; the ultrasonic energy reflected by the subject under examination is received by an array of electroacoustic transducers. The latter are actuated or the received signals are read with predetermined delays according to a received signal focusing rule. The focused received signals are turned into image data for ultrasonic image display. The transmitting transducers are actuated with such delays as to generate a homogeneous acoustic field over all or part of the region of the subject under examination, which may be covered by the geometry of the whole array of transducers.

摘要： Microbeamformers coupled to groups of array elements which partially beamform groups of elements for the formation of multiple receive lines are provided. In the microbeamformers, a delay line can be configured to output multiple signal streams that can be delayed by different amounts to support multiline receive in a microbeamformer. A read process during beamforming is not destructive, thereby allowing multiline receive beams to be generated from a single delay line.

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： An ultrasound imaging system (100) includes at least first and second arrays (108) of transducer elements, which are angularly offset from each other in a same plane. Transmit circuitry (112) excites the first and second arrays to concurrently transmit over a plurality of angles. Receive circuitry (114) controls the first and second arrays to concurrently receive echo signals over the plurality of angles. An echo processor (116) processes the received signals, producing a first data stream for the first array and a second data stream for the second array. The first and second data streams include digitized representations of the received echo signals. A sample matcher (118) compares samples of the first and second data streams and determines a cross-correlation there between. A correlation factor generator (120) that generates a correlation factor signal based on the determined cross-correlation. A scan converter (122) generates a 3D image for display based on the correlation factor signal and the first and second data streams.
