Phase-locked loop techniques applied to ultrasonic Doppler signal processing

A Sainz et al. Ultrasonics. 1976 May.

Abstract

A new method of measuring blood flow velocity and acceleration using analogue and phase locked loop techniques is described. Instantaneous peak velocity, instantaneous mean velocity and acceleration can be obtained on-line and displayed on simple recording systems.
