Basic Principles of Echocardiography
Echocardiography which is the most commonly used noninvasive cardiac imaging modality is called ultrasonography of the heart. It provides real-time images from the heart and gives comprehensive information regarding the cardiac structure, function and the hemodynamic at a relatively inexpensive cost. Echocardiography uses harmless ultrasound waves (1–10 MHz) to visualize the heart.
This book is a practical echocardiography book; nonetheless, sonographers and clinicians should be familiar with the basic physics of ultrasound to obtain better images and avoid artifacts. In this chapter we tried to point out some useful data regarding ultrasound Physics, transducer Types, Echocardiography Modes, Tissue Harmonic Imaging, Principles of Doppler Echocardiography and Doppler-Based Hemodynamic Assessment.
