Doppler Ultrasound – This imaging process measures slight modifications in the frequency of the ultrasound waves as they bounce off shifting objects, corresponding to blood cells. There is often a finest angle from which to view aspects of the intrauterine contents and fetal structures. For example, transverse views of the kidneys are best obtained from a directly anterior or posterior direction. With a lateral view, one kidney is shadowed by the backbone ( Fig. 9-13 ).
