Principles of Sonography Exam Bank
Course Introduction
Principles of Sonography introduces students to the fundamental concepts and techniques used in diagnostic medical ultrasound. The course covers the physical principles of sound waves, their interaction with human tissues, and the mechanisms behind ultrasound image formation. Students explore key topics such as equipment operation, image optimization, patient positioning, and the safe use of sonographic technology. Emphasis is placed on understanding various sonographic modalities, recognizing image artifacts, and interpreting anatomical structures across multiple organ systems. The course lays the groundwork for clinical practice and further study in specialized areas of sonography.
