    摘要: An ultrasonic diagnostic imaging system is provided by which an ultrasonic image and Doppler flow information are simultaneously displayed from echo acquisition sequences alternating between image signal acquisition and Doppler signal acquisition. To continuously display Doppler information during the intervals that images signal acquisition is occurring, these gaps in Doppler signal acquisition are filled by signals derived from the Doppler signals received prior to and succeeding the gaps. The Doppler signals received prior to the gap are used to produce spectrally continuous signals extending over the initial portion of the gap. The Doppler signals received following the gap are used to produce spectrally continuous signals extending over the final portion of the gap. A gapsize calculator is responsive to variations in system scanning parameters to set the durations of the successive image and Doppler signal acquisition intervals to obtain optimal frame rates of display.

    摘要: 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.

    摘要: A technique for continuously determining and displaying the peak velocities of spectral Doppler information is disclosed. A Doppler noise threshold level is determined from operating characteristics of the ultrasound system, probe, or both. Received spectral Doppler data for a spectral line is compared to this threshold to identify a valid peak velocity value. Spectral lines are examined in advance of their display to detect excursions due to artifacts such as valve clicks. Peak velocity values are interpolated and displayed in place of artifact peak values. Individual heart cycles over which quantified measures of cardiovascular performance are computed and displayed are selected by the R-wave intervals of an ECG trace. The interval of the concurrent spectral Doppler display corresponding to the heart cycle interval over which the quantified measures are computed or pertain is automatically highlighted for the user.

    摘要: A technique for scanning an image field with adjacent beams of ultrasonic energy is provided in which initially transmitted beams are transmitted along beam directions down the center of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at increasing lateral locations in said field with respect to the locations of the initially transmitted beams until the full image field has been scanned. In one alternative embodiment initially transmitted beams are transmitted along beam directions at the lateral sides of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at lateral locations which converge toward the center of the image field until the full image field has been scanned. In another alternative embodiment initially transmitted beams are transmitted on one side of the center of the image field, subsequent beams diverge from the locations of the initially transmitted beams, and concluding beams laterally converge at a location on the other side of the center of the image field.

    摘要: A method and apparatus are provided for processing ultrasonic diagnostic image information acquired in a plurality of scan planes for presentation as a three dimensional display of a volumetric region of the body. The image points in each scan plane are repositioned by approximating the rotation and translation of the scan plane in correspondence with the angle from which the volumetric region is to be viewed. This approximation is accomplished using conventional scan conversion processors by scaling the spatial coordinates of the original ultrasonic image in one or more dimensions and translating the image in one or more directions in correspondence with the viewing angle. A plurality of such scaled and translated images are accumulated and displayed in a combined three dimensional image presentation.

    摘要: An ultrasonic diagnostic imaging system is provided which calibrates and quantifies colors of a color power Doppler display to produce quantified measurements of Doppler power intensity. The colors of a color power Doppler image are divided into discrete colors and each color assigned a quantified measure of the Doppler power intensity indicated by that color. When a user moves a cursor over the image the system compares the color of the pixel where the cursor is located with the range of colors and their quantified measures and produces a quantified measure of the Doppler power intensity at the location of the cursor. A line of such measures across a blood vessel can be used to plot a profile of Doppler power intensity across the vessel, and an index number which is a measure of perfusion in a region of the body is determined from an area of a color power Doppler image.

    摘要: A method and apparatus are described for testing the integrity of an ultrasonic transducer probe (10) or the ultrasound system connected to the probe. The elements of the transducer are pulsed at a time when the probe is not in contact with a patient and the surface of the probe lens is exposed to the open air. The channel electronics receives the echo signal returned from the lens-air interface and reverberations between this interface and the transducer. These signals are analyzed by a diagnostic processor (20) coupled to the channel electronics for characteristics such as amplitude, time of echo reception, group delay, and other characteristics to determine the possible existence of problems such as faulty transducer elements or connections and problems in the system receive electronics. The diagnostic processor can adaptively adjust an operating characteristic of the system electronics such as gain or time delay to compensate for a detected out of tolerance condition.

    摘要: An ultrasonic diagnostic imaging system is provided in which a portion of an ultrasonic image can be selected for enlarged display as a "zoom" image. When the image portion is displayed in its enlarged format, the bandwidth of a filter in the ultrasonic information path is extended to increase the information content of the image portion when displayed in its enlarged format. The bandwidth is continuously optimized to maximize information content in consideration of the characteristics of the display while preventing the generation of scintillation artifacts caused by attempts to display information of an excessive bandwidth.

    摘要: An array of ultrasonic transducer elements receives signals to form beams simultaneously from a plurality of beam directions. The echo signals received by each transducer element are sampled in response to two or more interleaved sampling signal sequences, each of which is timed to begin at the initial time of arrival of echo signals from a unique spatial line. Each sampling signal sequence thereby produces signal samples associated with a given line. The stream of interleaved signal samples from each transducer element are separated in correspondence with each sampling signal sequence, and signal samples from corresponding separated sequences from the transducer elements are summed to form coherent signals corresponding to spatially separate ultrasonic beams.
