Abstract

This invention relates to a method of automatically setting the gain of an echo signal in a Doppler ultrasound haemodynamic monitor. In essence the invention comprises monitoring the strength of velocity components measured by the apparatus, and identifying a group of such components occupying a particular band within the overall velocity spectrum. The signal gain is then adjusted so that the perceived width of the band falls within predetermined limits. The monitoring or assessment of the velocity components is preferably undertaken when the overall flow velocity is high e.g. during systole.
