Abstract
A method and system for generating data for a spectral Doppler strip in an ultrasound system includes a beamformer that provides Doppler data to a signal processor. The signal processor applies an autoregressive model and determines autoregressive parameters responsive to the Doppler data. Information responsive to the autoregressive parameters is generated, and a window function is applied to the information. At least one spectrum responsive to the auto-regressive parameter is estimated with a Fourier transform.

An ultrasound apparatus for generating data for a spectral Doppler strip comprising:
- a beamformer with a Doppler data output;
- and
- a signal processor for generating auto-regressive parameters from Doppler data at said output and for applying a window function to information responsive to said auto-regressive parameters.
An ultrasound apparatus for generating data for a spectral Doppler strip comprising:
- a beamformer with a Doppler data output;
- and
- a signal processor for generating extrapolated data from Doppler data at said output and for applying a window function to said extrapolated data.
