Radiographic Quality Assurance
Final Exam Questions
Course Introduction
Radiographic Quality Assurance is a course designed to equip students with a comprehensive understanding of the principles and practices essential for maintaining high standards in medical imaging. The course covers key topics such as quality control procedures, evaluation of imaging equipment performance, image quality assessment, and radiation safety protocols. Emphasis is placed on regulatory requirements, routine testing methods, troubleshooting common issues, and documentation processes necessary to ensure diagnostic accuracy and patient safety. Through theoretical knowledge and practical applications, students learn to implement and monitor effective quality assurance programs in radiology departments.
