Provides the Doppler ultrasound user with a firm grasp of its underlying physical principles. This book provides a sound theoretical basis for clinical users of Doppler ultrasound, and includes an up--to--date survey of the many new innovations that have been described as potentially useful for detecting, measuring and imaging blood flow. "...an essential component in the library of any serious worker in Doppler ultrasound." "...no other work comes close to this in the depth and breadth of technical and physical detail with which this topic is described." -- Physiological Measurement, August 2000
