摘要： A three dimensional ultrasonic imaging system includes a matrix array transducer which is capable of scanning beams over a maximal volumetric region. The array transducer is operable to selectively scan one of a plurality of subvolumes of the maximal volumetric region at a real time scanning rate such that a live 3D image of the subvolume is processed and displayed. A user control is actuated to step the system through the scanning of a sequence different subvolumes. In an illustrated embodiment the maximal volumetric region encompasses the heart, and the system can be stepped through the scanning and display of live 3D images of front, center, and back subvolumes of the heart.

摘要： A medical diagnostic ultrasonic imaging system acquires receive beams from spatially distinct transmit beams. The receive beams alternate in type between at least first and second types across the region being imaged. The first and second types of receive beams differ in at least one scan parameter other than transmit and receive line geometry, and can for example differ in transmit phase, transmit or receive aperture, system frequency, transmit focus, complex phase angle, transmit code or transmit gain. Receive beams associated with spatially distinct ones of the transmit beams (including at least one beam of the first type and at least one beam of the second type) are then combined. In this way, many two-pulse techniques, including, for example, phase inversion techniques, synthetic aperture techniques, synthetic frequency techniques, and synthetic focus techniques, can be used while substantially reducing the frame rate penalty normally associated with such techniques.

摘要： An ultrasonic diagnostic imaging system transmits a plurality of focused beams normal to the plane of a transducer aperture and receives multiple receive lines in response to each transmitted beam. Sub-apertures of the transducer aperture are defined by apodization and signals of the sub-apertures are aligned and combined to produce signals exhibiting the effect of transmit steering at different angles with respect to the sub-apertures. The steered signals are detected and the detected signals relating to common points in an image field are combined. The combined detected signals are used to produce an ultrasound image with reduced speckle.
