Radiology Quality Assurance
Pre-Test Questions
Course Introduction
Radiology Quality Assurance focuses on the systematic monitoring, evaluation, and improvement of radiology services to ensure high standards of patient care and diagnostic accuracy. This course covers the principles and practices of quality control in radiographic imaging, including equipment calibration, image quality assessment, radiation safety, regulatory compliance, and workflow optimization. Students will learn methods for identifying errors, implementing corrective actions, and maintaining thorough documentation to meet professional guidelines and accreditation requirements. Emphasis is placed on interdisciplinary teamwork, patient safety, and the continual advancement of imaging practices in clinical environments.
