Vascular resistances of various fetal areas are assessed by Doppler ultrasound. The PI, RI and S/D indices are measured on the cerebral, renal, aortic and umbilical Doppler spectrum. Ratios of these indices based on the comparison of the cerebral (Rc) and the umbilical (Rp) resistances, or carotid (Rcc) and umbilical resistances, or cerebral (Rc)
The color Doppler image is dependent on general Doppler factors, particularly the need for a good beam/flow angle. Curvilinear and phased array transducers have a radiating pattern of ultrasound beams that can produce complex color flow images, depending on the orientation of the arteries and veins.

These sound waves, called ultrasound, are generated by microscopic vibrations of a ceramic crystal. When ultrasound waves reflect off moving objects such as the fetal heart or blood flow, the waves are altered slightly in frequency. The A Doppler ultrasound can estimate how fast blood flows by measuring the rate of change in its pitch (frequency).

Fetal and vascular Doppler technology is based on the Doppler shift principle first discovered by Christian Doppler, an Austrian physicist, in 1842. The principle is similar to hearing a train bell approaching, and then moving away from you, and how the audible pitch of that train bell changes from high to low.

Dopplers operate on the principle of listening to reflections of small, high frequency sound waves. These sound waves, called ultrasound, are generated by microscopic vibrations of a ceramic crystal. When ultrasound waves reflect off moving objects such as the fetal heart or blood flow, the waves are altered slightly in frequency. The
