The development and widespread adoption of iterative reconstruction (IR) algorithms for CT
have greatly facilitated the contemporary practice of radiation dose reduction during …

Abstract Background In August 2017, the European Commission awarded the “European
Study on Clinical Diagnostic Reference levels for X-ray Medical Imaging” project to the …

Background Assessment of liver lesions is constrained as CT radiation doses are lowered;
evidence suggests deep learning reconstructions mitigate such effects. Purpose To evaluate …

Objective To determine patient, institution, and machine characteristics that contribute to
variation in radiation doses used for computed tomography (CT). Design Prospective cohort …

Purpose: The purpose of this study was to assess the clinical value of ultra–low-dose
computed tomography (ULDCT) compared with chest x-ray radiography (CXR) for …

Background Diagnostic reference levels (DRLs) and achievable doses (ADs) were
developed for the 10 most commonly performed pediatric CT examinations in the United …

The central dose quantities used in radiological protection are absorbed dose, equivalent
dose, and effective dose. The concept of effective dose was developed by the International …

Objectives The aim of this study was to investigate the impact on metal artifacts and dose
efficiency of using a tin filter in combination with high-energy threshold (TH) images of a …

In 1971, the first patient CT examination by Ambrose and Hounsfield paved the way for not
only volumetric imaging of the brain but of the entire body. From the initial 5-minute scan for …

The field of artificial intelligence (AI) is transforming almost every aspect of modern society,
including medical imaging. In computed tomography (CT), AI holds the promise of enabling …
