RADR 1313 Final Exam Review (260 Questions) – X-Ray Physics, Image Quality, CR/DR, Fluoroscopy | 2026 – Radiologic Technology

This document contains an extensive collection of approximately 260 exam-style questions and correct answers designed for comprehensive final exam preparation in RADR 1313. It covers core radiographic physics and imaging principles, including x-ray production, electromagnetic properties, wavelength and frequency relationships, and detailed components of the x-ray tube such as the anode, cathode, filament, and focusing cup. The material is presented in a structured Q&A format, enabling efficient memorization, active recall, and thorough review of essential concepts tested in radiography courses. The document also provides in-depth coverage of image quality factors such as contrast, brightness, spatial resolution, distortion, and grayscale, along with key exposure parameters like kVp, mAs, SID, and OID. It explores radiation interactions including Bremsstrahlung and Characteristic interactions, attenuation processes, Compton scatter, and the photoelectric effect. Additionally, it includes critical digital imaging concepts such as matrix, pixel characteristics, bit depth, sampling frequency, histogram analysis, LUT, exposure indicators, and post-processing techniques. Further, the material addresses advanced systems and clinical applications, including Computed Radiography (CR), Direct Radiography (DR), flat panel detectors, PACS, DICOM, RIS/HIS integration, and fluoroscopy principles such as AEC, ABC, brightness gain, and image intensifiers. Practical topics like grid usage, technique charts, exposure control, and common imaging artifacts are also thoroughly explained, making this a complete and high-yield review resource. This document is highly relevant for students enrolled in Radiologic Technology, Diagnostic Medical Imaging, Radiography, or Medical Imaging Science programs. It is suitable for courses such as RADR 1313 – Radiographic Imaging, Radiographic Physics, or Digital Imaging Systems offered at universities, community colleges, and allied health institutions. It is particularly beneficial for first-year and second-year radiography students preparing for final exams, competency assessments, or registry-level review. The content aligns closely with standard radiography textbooks such as Radiographic Imaging and Exposure by Terri L. Fauber and Digital Radiography: Physical Principles and Quality Control by Euclid Seeram, making it an excellent supplementary study guide for mastering both theoretical and applied imaging concepts.
