Principles of Radiologic Technology Test Bank
Course Introduction
Principles of Radiologic Technology introduces students to the fundamental concepts and practices involved in medical imaging and radiologic science. The course covers the basic physics of X-ray production, interaction of radiation with matter, and essential safety protocols to ensure patient and operator protection. Students explore the operation and maintenance of radiologic equipment, image acquisition techniques, and quality assurance standards. Emphasis is placed on understanding the principles of radiographic exposure, digital imaging systems, and the ethical and legal responsibilities of radiologic technologists in clinical settings.
