title: Radiation Protection in Computed Tomography.
abstract: Radiation exposure from computed tomography (CT) examinations has long been a concern. As part of their education, CT technologists learn the fundamentals of radiation interactions, dose, risk, and protection. Modern CT systems have evolved to include dose optimization features. This article reviews the fundamentals of radiation dose and introduces new CT dose optimization techniques.
