TY - CHAP M1 - Book, Section TI - Physics of Ultrasound A1 - Xu, Daquan A2 - Hadzic, Admir PY - 2017 T2 - Hadzic's Textbook of Regional Anesthesia and Acute Pain Management, 2e AB - Ultrasound application allows for noninvasive visualization of tissue structures. Real-time ultrasound images are integrated images resulting from reflection of organ surfaces and scattering within heterogeneous tissues. Ultrasound scanning is an interactive procedure involving the operator, patient, and ultrasound instruments. Although the physics behind ultrasound generation, propagation, detection, and transformation into practical information is rather complex, its clinical application is much simpler. Because ultrasound imaging has improved tremendously over last decade, it can provide anesthesiologists opportunity to directly visualize target nerve and relevant anatomical structures. Ultrasound-guided nerve block is a critical growth area for new applications of ultrasound technology and become an essential part of regional anesthesia. Understanding the basic ultrasound physics presented in this chapter will be helpful for anesthesiologists to appropriately select the transducer, to set the ultrasound system, and then to obtain a pleasing imaging.
