M marks are method marks upon which further marks depend. For an M mark to be scored, the point to which it refers must be seen in a candidate's answer. If a candidate fails to score a particular M mark, then none of the A marks that follow can be scored. B marks: are independent marks, which do not depend on other marks.

Doppler Ultrasound - Principles and practice

Doppler 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.
