US Classification:

600/453000

Abstract:

In an ultrasonic diagnostic imaging system, the parameters which govern the display of Doppler information are automatically optimized to make better use of the display range or area. Spectral Doppler information may be used to optimize a spectral display or a colorflow display, and colorflow Doppler information may be used to optimize a spectral display or a colorflow display. The optimization may be invoked by a manual user control which automatically optimizes one or a plurality of display parameters. Automatic optimization may be invoked only when called for by the user, or periodically after a time interval, a given number of heart cycles, or when the user has made a change to the display or imaging mode. Preferably the optimization processor runs continuously in the background so that optimized parameters are available immediately when called for. The optimization processor may utilize “hidden” Doppler data which has been acquired but is not used for display purposes.

International Classification:

A61B 8/00

US Classification:

600454

Abstract:

An ultrasonic diagnostic imaging system produces a spectral Doppler display on which a parameter such as peak or mean velocity is automatically traced. If the user is dissatisfied with the automatically drawn trace (), the user can manipulate a cursor () on the display screen to grab a point () on the trace and drag the trace to a new location relative to the spectral display or manually redraw a portion of the trace. In an illustrated embodiment the spectral Doppler trace () includes defined key timing points in the heart cycle which can be adjusted by the user in both the velocity and time dimensions of the display. Graphically displayed values and calculations of the display are automatically updated in response to adjustment of the trace.)

Appl. No.:

Inventors:

Marshall T. Robinson - Snohomish WA

Assignee:

Advanced Technology Laboratories, Inc. - Bothell WA

International Classification:

A61B 806

US Classification:

12866005

Abstract:

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.

International Classification:

G01F 100

US Classification:

12866108

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.

International Classification:

A61B 800

US Classification:

600454

Abstract:

An ultrasonic diagnostic imaging system and method are described by which a fundamental frequency signal is transmitted into the body and harmonic (nonlinear) echo returns are received from the transmission. The harmonic echo signals are Doppler processed and displayed. The harmonic Doppler signals may be displayed alone, or in combination with a fundamental frequency or harmonic grayscale image. In a preferred embodiment harmonic signals returned from moving tissue are segmented on an intensity or frequency basis and displayed. The inventive apparatus and method provide highly resolved ultrasonic images of moving tissue which are substantially unobscured by image clutter from structures or tissue in the near field.
