Technical Considerations, Equipment, and Physics of Duplex Sonography,information. This is achieved by combining Doppler ultrasound with imaging. The principles and instrumentation of Doppler ultrasound are presented in this chapter. Principles of realtime ultrasound imaging (1–6) and Doppler principles and instrumentation in greater detail (7–8) are described elsewhere.

Physicians or technologists reading this book should come away with a well-rounded background in state-of-the-art duplex sonography and will undoubtedly discover new possibilities for using this non-invasive 978-1-4612-8333-1978-1-4612-3750-1

These, in turn, are affected by other factors such as the individual’s physiologic status. Notable examples include altered circulatory impedance of the distal aorta and lower e

Technical Considerations, Equipment, and Physics of Duplex Sonography,omic information, whereas Doppler provides physiologic information in the form of blood flow data. Pulsed-Doppler instrumentation provides the ability to detect and measure flow at specific anatomic sites. To intelligently use this capability, it is necessary to know the anatomic origin of the flow
