OPTIMIZATION IN ULTRASOUND COLOR FLOW IMAGING
20190261952 · 2019-08-29 ·

Rather than trying to automate what an experienced user does, rules designed for processor implementation are used for color flow imaging optimization by an image processor of an ultrasound scanner. By determining a characteristic of a scanned target, a priori information is provided. This a priori information, such as a size of a primary target, is used to select the optimization to be used. Different types of optimization may be used for different characteristics of the primary target. The values for settings may be different for different characteristics.

TRIPLE MODE ULTRASOUND IMAGING FOR ANATOMICAL, FUNCTIONAL, AND HEMODYNAMICAL IMAGING

An ultrasonic imaging system acquires frames of echo data at a high acquisition frame rate using a single mode of acquisition. The echo data is used by three image processors to produce an anatomical image, a mechanical function image, and a hemodynamic image from the same echo data. A display displays an anatomical image, a mechanical function image, and a hemodynamic image simultaneously.

Automated biplane-PW workflow for ultrasonic stenosis assessment

An ultrasound system with a matrix array (500) probe (10) operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images (60a, 60b) of the vessel, one a longitudinal cross-sectional view (60a) and the other a transverse cross-sectional view (60b). The two image planes intersect along a Doppler beam line (68) used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data (62) is then acquired and displayed from the sample volume location.

An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.
