Basic Concepts in Doppler Echocardiography The objective of this textbook is to offer a detailed yet concise overview of the various applications of Doppler echocardiography. The fundamental principles of pulsed mode, continuous mode, and color flow mapping are fully explained as well as the clinical applications of each modality in the evaluation of various cardiac pathologies. A copious amount of figures and illustrations is included so that the reader is able to follow the discussions in the text by referring to the appropriate case studies. The emphasis of this book is focused upon the practical Doppler examination. The sections on theoretical considerations are therefore brief but comprehensive, while the didactic sections concentrate upon how to perform and interpret the clinical examination. The instrumentation of the Doppler system is also discussed so that the physician or technologist can acquire a basic understanding of how the Doppler system actually functions. CONTRmUTORS Bjorn AJ.
