Abstract
A system and method is disclosed that examines Doppler spectrum signals output by an ultrasound system when measuring blood flow velocity to determine a proper Doppler gain and to suppress noise manifest in the Doppler spectrum. Noise present in the Doppler spectrum is examined and used as a criterion for optimal gain. If the Doppler gain is too high or too low in accordance with predetermined levels, overall gain is adjusted accordingly.
