Computed radiography

Biomedicine & Pharmacotherapy, 1998
In several medical centers computed radiography has almost completely replaced the use of conventional screen-film systems for general radiography. The aim of this paper is to explain the basic principles of the four most frequently numerical detectors used in the world, with emphasis on the phosphor plates, which are the most frequently used both in ...

Computed radiography in pediatrics [PDF]

Journal of Digital Imaging, 1995
Computed radiography (CR) has various advantages such as dynamic range. Diagnostic accuracy with CR using reduced radiation dose is considered comparable with that of conventional film-screen radiography in diagnosing apparent chest abnormalities.

Dosimetry in CR mammography using radiochromic film

Brazilian Journal of Radiation Sciences, 2022
To estimate the dose that a patient's mammary tissue receives during mammographic screening, radiochromic film and objects simulators made of PMMA are used. This material interacts with X-rays in a similar way to tissue. Estimating the dose absorbed by a

Computed Radiography Exposure Indices in Mammography

South African Journal of Radiology, 2008
Studies indicate that computed radiography (CR) can lead to increased radiation dose to patients. It is therefore important to relate the exposure indicators provided by CR manufacturers to the radiation dose delivered so as to assess the radiation dose ...

A Multi Institutional Comparison of Imaging Dose and Technique Protocols for Neonatal Chest Radiography [PDF]

, 2019
Published ArticleIntroduction: The focus on paediatric radiation dose reduction supports reevaluation of paediatric imaging protocols. This is particularly important in the neonates where chest radiographs are frequently requested to assess respiratory
