Other Ultrasonic Techniques and Current Research,New developments are always of interest to anyone in a diagnostic field. This chapter is designed to bring you up-to-date with the current research which is being done in alternative systems of arterial imaging and to acquaint you with the research direction being followed at the Institute of Applied Physiology and Medicine.

Vascular Murmurs,Vascular murmurs, also called bruits, are audible sound, other than the normal pulse transients, generated in the arteries or veins. They usually have a random, blowing quality but may, in addition, contain a superimposed resonance.
