Systems, methods, and apparatuses for confidence mapping of shear wave measurements are disclosed. Confidence maps of shear wave image measurements may be generated from one or more confidence factors. Masking of graphical overlays of tissue stiffness values, based at least in part on the confidence map is disclosed. The confidence map and/or masked graphical overlays of tissue stiffness values may be superimposed on ultrasound images and provided on a display.

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.
