Systems and methods are provided for compressing and decompressing data in an ultrasound beamformer. The systems and methods include an encoder for compressing delay data based at least in part on a smoothness of a delay profile, and for compressing apodization data based at least in part on a smoothness of an apodization profile.

Delay and apodization control interface for ultrasound beamformer

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.

Ultrasound system with dynamically automated doppler flow settings as a sample volume is moved

An ultrasound system with a matrix array () probe () operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images () of the vessel, one a longitudinal cross-sectional view () and the other a transverse cross-sectional view (). The two image planes intersect along a Doppler beam line () 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 () is then acquired and displayed from the sample volume location.
