Doppler Ultrasound - Principles and practice
fetalmedicine.orgDoppler ultrasound in general and obstetric ultrasound scanners uses pulsed wave ultrasound (Figure 4). This allows measurement of the depth (or range) of the flow site. Additionally, the size of the sample volume (or range gate) can be changed. Pulsed wave ultrasound is used to provide data for Doppler sonograms and color flow images.
