Radiologic Technology
Chapter Exam Questions
Course Introduction
Radiologic Technology is a comprehensive course that introduces students to the principles and practices of medical imaging using ionizing radiation. The curriculum covers the operation of radiographic equipment, patient positioning, image acquisition, radiation safety, and quality assurance. Emphasis is placed on understanding human anatomy, radiologic physics, and pathology as they relate to medical imaging. Students also gain practical skills in producing diagnostic images while adhering to ethical standards and regulatory requirements. The course prepares students for professional roles in healthcare settings, providing foundational knowledge necessary for certification and practice as radiologic technologists.
