摘要： An ultrasonic imaging method and apparatus are described for imaging the coronary arteries of the heart. The vascular system is infused with an ultrasonic contrast agent. A volumetric region of the heart wall including a coronary artery is three dimensionally scanned. A projection image of the volumetric region is produced from the scanning, providing a two dimensional contrast image of the coronary artery with the appearance of an angiogram. Preferably the coronary artery signals are segmented from contrast signals emanating from the myocardium and the heart blood pool so that the coronary arteries are clearly highlighted and distinct in the ultrasonic angiogram.

摘要： Ultrasonic cardiac image information is acquired and segmented by automatic border detection. The segmented ultrasonic information is used to display regional wall motion over time. The segmented information may be presented in a color-coded representation, or entered automatically as qualitative or quantitative measures on a scorecard of cardiac performance. The inventive technique is applicable to both two dimensional and three dimensional ultrasonic image information.

摘要： An ultrasonic diagnostic imaging system and methods are described which produces ultrasonic images from harmonic echo components of a transmitted fundamental frequency. Preferably, a programmable digital filter is used to pass harmonic echo components for image processing to the exclusion of fundamental frequency signals. In a preferred embodiment, artifacts are removed by producing decorrelated replicas of the harmonic signals, which are then combined and used for imaging. To produce an image in the presence of depth dependent attenuation of high frequency echo signals, both fundamental and harmonic echo signals are processed and used to produce an image blended from components of both fundamental and harmonic echo signals.

摘要： An ultrasonic transducer assembly (10) for diagnostic imaging is provided. The ultrasonic transducer includes an elongated housing (12) that is configured and dimensioned to accommodate applicable anatomical constraints. The assembly includes a sensor assembly (20) that includes a two-dimensional matrix array of transducer elements (22) and a translation mechanism (32) to physically translate the two-dimensional matrix array of transducer elements (22) through a field of view of approximately 140 degrees by 80 degrees. An articulation control mechanism (38) allows a clinician to move the tip (14) of the ultrasonic transducer (10) into a desired imaging position, e.g., for fetal imaging.

摘要： A digital multiline beamformer is provided which produces multiple receive beams in response to a single transmit event. An embodiment of the present invention includes a bulk delay which provides a common steering delay applicable to all of the beams received at one time. The bulk delay is succeeded by parallel filter processing paths which produce finely focused multiple beams simultaneously. In one embodiment a multiphase filter produces the samples for multiple beams, which is advantageous when the number of simultaneously produced beams is greater than the number of phases produced by the fine focus filter.

摘要： An ultrasound system which performs two dimensional imaging is upgradeable to a system which also performs three dimensional ultrasonic imaging. The ultrasound system contains space in which an optional 3D beamformer may be installed to provide the ultrasound system with three dimensional imaging capability. When the 3D beamformer is installed a scanhead select module connects one of a plurality of scanhead connectors to the proper beamformer for the imaging procedure commanded by the user.

摘要： An ultrasonic 2D array has elements extending in two dimensions which can be individually controlled and operated to form a 2D array for scanning a volumetric region in three dimensions. Individual ones of the elements can also be selected and operated together to form a 1D array for scanning a planar region in two dimensions. The array transmits scanlines to scan the volumetric region and the planar region in a time interleaved manner with the frame rate of the planar region be higher than that of the volumetric region. A spectral display may also be produced of a sample volume located in the planar region.
