An ultrasound system is disclosed that includes a method and apparatus to automatically adjust certain parameters that affect visualization of a Doppler spectral image. The ultrasound system acquires spectral lines of Doppler data generated by the ultrasound system. A data processor within the ultrasound system determines the presence of aliasing and estimates noise levels from the spectral lines of Doppler data. The data processor then automatically adjusts system parameters such as pulse repetition frequency (PRF), baseline shift, and spectrum orientation in response to aliasing and noise levels. The data processor of the ultrasound system also determines positive and negative signal boundaries for each spectral line of Doppler data and a display architecture processes the signal boundary data to display a spectral trace corresponding to the edges of the spectral lines.
In an ultrasound system for generating a Doppler spectral image, a method to automatically establish a parameter used in connection with display of a Doppler spectral image, said method comprising:
In an ultrasound system for generating a Doppler spectral image, apparatus to automatically establish a parameter used in connection with display of a Doppler spectral image, said apparatus comprising a data processing module acquiring a plurality of spectral lines of Doppler data, and determining a signal-free subset of Doppler data from said plurality of spectral lines of Doppler data, and estimating at least one noise level from said signal-free subset of Doppler data, and automatically adjusting a parameter of a Doppler spectral image, including at least one of a pulse repetition frequency, a baseline shift and spectrum orientation, based on said at least one noise level.
