Radiography I Practice Exam Course Introduction Radiography I introduces students to the fundamental principles and practices of medical radiography, focusing on the basic physics of x-ray production, image formation, and radiation safety. Emphasis is placed on understanding the operation of radiographic equipment, patient positioning techniques, and the application of proper exposure factors to produce optimal diagnostic images. The course also covers essential topics such as radiation protection, quality assurance, and legal and ethical considerations in radiographic procedures. Through a combination of theoretical instruction and hands-on laboratory experiences, students gain foundational skills required for competent practice in the field of radiologic technology.
