Summary

Gain a firm foundation for sonography practice! Corresponding to the chapters in Hedrick's Technology for Diagnostic Sonography, this study guide focuses on basic concepts to help you master sonography physics and instrumentation. It includes laboratory exercises designed to teach you how to operate a scanner, and comprehensive review questions allow you to assess your knowledge. Not only will you learn the theoretical knowledge that is the basis for ultrasound scanning, but also the practical skills necessary for clinical practice. Laboratory exercises teach you the function of operator controls and how to optimize image quality and practice ALARA, and include step-by-step instructions for scanner operation, for hands-on application and practice. 250 review questions help you assess your understanding of sonography physics and instrumentation, and identify areas of knowledge that may need further study. Key Points at the beginning of each chapter emphasize the most important sonography principles that you need to understand and apply.
