Embodiment Construction

[0011] first reference figure 1 , shows in block diagram form an ultrasound system constructed in accordance with the principles of the present invention. The ultrasound probe 10 contains a transducer array 12 of transducer elements that transmit ultrasound waves into the body and receive returning echo signals. The emitted waves are directed into a beam or scanline to interrogate a region of interest in the body. One-dimensional arrays can be used to emit beams in a single plane for two-dimensional imaging. For the stenosis assessment examination according to the present invention, the probe 10 is a matrix array probe having a two-dimensional array of transducer elements 500 coupled to a probe microbeamformer 502 . Matrix array probes can be used to transmit beams over volumetric regions of the body for three-dimensional imaging. As explained more fully below, the beam can be steered and focused in different directions by the probe to interrogate tissue in a particular loc...

Abstract

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.
