    摘要: Three dimensional ultrasonic images are formed by volume rendering using a 3D ultrasonic image data set. The data set may be acquired by rocking, sweeping, fanning or rotating a 2D image plane through the volume being scanned, or by steering beams in different angular directions from a two dimensional array of transducer elements. The polar data is volume rendered to form a 3D image by means of projected raylines which are warped to account for the angular geometry of the acquisition.

    摘要: An ultrasonic diagnostic imaging system acquires 3D data sets of the fetal heart by use of a gating signal synthesized from detected motion of the fetal heart. A sequence of temporally different echo signals are acquired from a location in the anatomy where motion representative of the heart cycle is to be estimated, such as a sample volume in the fetal carotid artery or an M line through the fetal myocardium. A heart cycle signal is synthesized from the detected motion and used to gate the acquisition of fetal heart image data at one or more desired phases of the fetal heart cycle. In an illustrated embodiment 3D data sets are acquired from multiple subvolumes, each over the full fetal heart cycle, then combined to produce a live 3D loop of the beating fetal heart.

    摘要: The present invention is a method of and system for imaging an object with an ultrasound transducer array that transmits ultrasound beams and detects echoes reflected from the object. A plurality of adjacent ultrasound beams are transmitted at the object, each of the beams being separated from an adjacent beam by a first predetermined distance. A plurality of groups of echoes are received from the object, with each of the groups of echoes corresponding to one of the plurality of the ultrasound beams. Each of these echoes are spaced from the corresponding ultrasound beam by a second predetermined distance which is less than the first predetermined distance. The transmitted ultrasound beams are arranged such that one of the received echoes corresponding to an ultrasound beam substantially overlaps with one of the received echoes corresponding to an adjacent ultrasound beam. At least a subset of the received echoes are then processed to obtain B-mode data from each of the processed echoes. In addition, the overlapping pairs of received echoes are processed to obtain B-flow data, typically by determining the difference between the overlapping received echoes. Doppler flow data, Doppler power data, and/or Doppler tissue motion data may also be processed from the received echoes.
