Pulsed (gated) and spectral Doppler Pulsed Doppler ultrasound is a technique for measuring the velocity of blood in a small sample volume (Figure 1). Shown in Figure 2 is the spectral Doppler measurement of blood flow in the common carotid artery.he location of the Doppler sample volume is illustrated by a cursor overlaid on the B-mode image shown as Figure 1. To provide a localised velocity measurement, the instrument transmits a pulse that is 6 wavelengths to 40 wavelengths long-depending on the desired length of the sample volume.
