Owing to recent advances in computing power, iterative reconstruction (IR) algorithms have
become a clinically viable option in computed tomographic (CT) imaging. Substantial …

In 1971, the first computed tomography (CT) scan was performed on a patient's brain.
Clinical CT systems were introduced in 1974 and dedicated to head imaging only. New …

OBJECTIVE. Radiation exposure from CT examinations should be reduced to a minimum in
children. Iterative reconstruction (IR) is a method to reduce image noise that can be used to …

Purpose In this study an evaluation of the imaging performance of an electronic portal
imaging device (EPID) is presented. The evaluation performed employing the QC-3V image …

Background Iterative reconstruction has become the standard method for reconstructing
computed tomography (CT) scans and needs to be verified for adaptation. Objective To …

BACKGROUND AND PURPOSE: Noncontrast CT of the head is the initial imaging test for
traumatic brain injury, stroke, or suspected nonaccidental trauma. Low-dose head CT …

Introduction Computed tomography (CT) dose optimization is an important issue in
radiography because CT is the largest contributor to medical radiation dose and its use is …

Objectives: For patients with intracranial hemorrhage (ICH), routine follow-up computed
tomography (CT) scans are typically required to monitor the progression of intracranial …

Purpose: To assess how ASIR (adaptive statistical iterative reconstruction) contributes to
dose reduction and affects image quality of non-contrast cranial computed tomography …

Purpose To evaluate the relationship between patient age and radiation doses associated
with routine pediatric head CT performed with automatic tube potential selection and tube …
