Clinical Sonography Test Bank
Course Introduction
Clinical Sonography is an in-depth course focusing on the principles and practices of diagnostic medical ultrasound. Students will explore sonographic physics, instrumentation, patient care, and image acquisition techniques across various body systems, including abdominal, obstetrical, gynecological, vascular, and small parts imaging. Emphasis is placed on correlating clinical findings with sonographic appearances, optimizing scanning protocols, and ensuring patient safety. Through a combination of theoretical instruction and hands-on laboratory experience, students develop proficiency in image interpretation, technical skills, and communication necessary for professional practice in clinical sonography.
