title: Computed Tomography Iterative Reconstruction Techniques.
abstract: For all their diagnostic value, computed tomography (CT) examinations have relatively high radiation exposure. Past efforts to decrease patient dose emphasized advances in data acquisition technology because attempts to decrease dose resulted in increased image noise from filtered back projection reconstruction techniques. Iterative reconstruction techniques lead to reduced dose and maintain image quality. Improvements in CT technology and protocols can enhance patient care, but the increased amount of data requires new methods for handling information. CT iterative reconstruction techniques present a powerful way to improve patient care and image quality.
