Radiographic Imaging Exam Preparation Guide
Course Introduction
Radiographic Imaging is a foundational course that explores the principles and techniques used to create diagnostic images through the use of X-rays and related modalities. The course covers the physics of X-ray production, image formation, and the factors affecting image quality, such as contrast, resolution, and exposure. Students will learn about different types of radiographic equipment, image receptors, and digital imaging technologies. Emphasis is placed on radiation safety, proper patient positioning, and adherence to protocols to ensure accurate and high-quality diagnostic results. Practical components may include laboratory sessions and hands-on practice to reinforce theoretical knowledge and develop technical skills essential for clinical radiography.
