A method for describing the absorbed dose delivered by x‐ray transmission computed
tomography (CT) is proposed which provides a means to characterize the doses resulting …

The computed tomography (CT) radiation dose to pediatric patients has received
considerable attention recently. Moreover, it is important to be able to determine CT …

A simple method of comparing and/or monitoring the radiation output level of a Computed
Tomography (CT) system, using a specially developed pencil‐shaped ionization chamber, is …

The energy deposited in the patient by the rotating x-ray beam in computed tomography
produces more uniform absorbed dose values within the section of imaged tissue than those …

Dose values in CT are specified by the manufacturers for all CT systems and operating
conditions in phantoms. It is not trivial, however, to derive dose values in patients from this …

Scatter to primary radiation ratios at detector positions were calculated for uniform cylindrical
water phantoms in both third and fourth generation X-ray CT scanners using the Monte …

In x-ray computed tomography (CT), the most common parameter used to estimate and
minimize patient dose is the CT dose index (CTDI). The CTDI is a volume-averaged …

The current paradigm for characterizing radiation dose in computed tomography (CT) is
based on a metric—the computed tomography dose index (CTDI)—introduced nearly thirty …

A survey of the pattern and frequency of computed tomography (CT) examinations in
Sweden has been conducted covering 89 of the 90 existing CT scanners (in 1991). The …

To date, in Computed Tomography (CT) various tech-niques have been utilized for
measuring and reporting exposure. This report outlines some techniques for measuring …
