Abstract: 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.

Abstract: 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.

Abstract: An ultrasonic diagnostic system is provided which detects the presence of coated microbubble contrast agents in the body of a patient by transmitting ultrasonic energy which causes the destruction of the coated microbubbles and detects the microbubble destruction through phase insensitive detection and differentiation of echoes received from two consecutive ultrasonic transmissions. The destruction of a microbubble can also be used as a point source of acoustic energy for aberration correction, whereby the timing of the beamformer is adjusted from an analysis of beamformer signals resulting from a detected microbubble destruction event.

Abstract: A backing block (10) for an ultrasonic array transducer comprises a flex circuit embedded in a body of acoustic backing material, with conductive traces on the flex circuit (20) terminating at the surface (12) of the body (10) at which an array transducer is mounted and extending out from the rear (14) of the body (10) for connection to electrical circuitry. The array transducer is formed of a composite material in which the pattern of the composite material is oriented at an oblique angle to the kerfs of the transducer.
