Method and apparatus for estimation and display of spectral broadening error margin for doppler time-velocity waveforms

摘要

A method of calibrating Doppler time-velocity waveforms obtained using a duplex ultrasound scanner. A spectral broadening error margin for the maximum velocity waveform is determined based on a unified theory of intrinsic spectral broadening for pulsed Doppler signals. The error margin is colorized or highlighted in the Doppler waveform display.
