This book represents tangible results of the Institute of Applied Physiology and Medicine's objectives of bringing into clinical application the concepts and results of bioengineers and physiologists. lt has grown out of our experience in development of original Doppler diagnostic instrumentation and its application to more than 6,000 patients in non-invasive diagnosis of the extracranial cerebrovascular circulation. It gath- ers together bioengineering and physiological concepts which were initially developed for a graduate course for physicians and specialized medical tech- nicians. lt...

My personal interest in cardiac Dopplerarose from longexperience in diagnos- ing carotid artery disease using Doppler continuous wave ultrasound with fre- quencey spectral analysis. The work of Dr. Liv Hatle of Trondheim, who was then using analogue tracings for cardiac Doppler, inspired me to try CW Doppler combined with spectral analysis and high-pass filtering techniques. The results with this system, without benefit of standard echocardiography were so pro- ductive that a special instrument was produced by Carolina Medical Electronics for worldwide marketing. Our experience led to the...

This book is designed as a definitive report on current capabilities of ultrasound imaging and Doppler evaluation of the cerebral circulation, both extracranial and intracranial. The basic chapters are directed to the beginner in ultrasound and hemodynamics and for the expert in updating newly available modalities and techniques new to the field. The ultrasonic and hemodynamic principles are presented for physicians and vascular technologists in a practical way to avoid unnecessary mathematics. The aim is for maximum clinical utilization so that available equipment may be used more...
