Abstract: A medical diagnostic ultrasound system is described in which ultrasonic B mode tissue information and Doppler flow information is acquired from a volumetric region of the body and processed together to render a three dimensional image. The three dimensional rendering processes the B mode and Doppler flow information as a function of the spatial location of B mode and Doppler pixels in the volumetric region. The rendering utilizes separate three dimensional rendering parameters for the tissue and flow information, respectively.

Abstract: An ultrasonic diagnostic imaging system is provided for measuring the volume of a chamber of the heart or other organ or vessel. An ultrasonic transducer probe is used to scan the chamber with a plurality of spatially distinct scan planes. The pixels of the chamber volume of each scan plane are aggregated to provide a measure of the volume. In a preferred embodiment the chamber volume pixels are developed from Doppler signals from the fluid within the chamber, and are related to voxels within the chamber by weighting pixels in the scan planes in accordance with the voxel sampling afforded by the inter-plane separation.

Abstract: An ultrasonic diagnostic imaging system is provided which utilizes a multivariate processor to discriminate between Doppler power signals which were produced by moving tissue, and Doppler power signals which were produced by fluid flow. Discriminated moving tissue Doppler power signals are displayed in a three dimensional spatial presentation.

Abstract: An ultrasonic endoscopic probe is provided with an articulating distal tip (14) at which an ultrasonic transducer (130) is located. The articulating section (30) of the probe can be locked in an articulated position by a lock control (28,28') located at a control section (10) of the probe. The locking force is variably selectable by the user, so that the articulating section (30) will be locked in position by a desired force. The articulating section (30) is controlled by cables (74,76,129), which include cable tension adjustments (70a,70b) that also serve to delimit the range of articulation. The articulating section (30) is formed of alternating pivot rings (120) with intervening polymeric pivot beads (106), which provide repetitively smooth articulation. The ultrasonic transducer (130) is rotatable to steer the acoustic scan plane during use, and a sliding membrane (164) between the transducer (130) and its acoustic window (162) allows the transducer (130) to rotate smoothly without sticking.

Abstract: A method and device for three dimensional ultrasonic scanning of a patient is described by which an ultrasonic probe scans image planes oriented in a wedge or fan shaped volume. The probe (100) is moved in an arc of travel about an apex (106) which is below the scanning device (10,12) and may be adjustably located within the probe (100) or lower, such as between the ribs of the patient. The inventive method and device enable a significant volume of the heart to be scanned intercostally and viewed in a three dimensional image format.
