摘要: In recent years, starting from 2001, conventional film-screen radiography has been rapidly replaced by digital (mostly computed radiography, CR) techniques in Estonia. New strategies for optimisation and quality assurance have introduced the DIMOND III SENTINEL partners recently. It includes consideration to diagnostic requirements of a given clinical situation, but also objectivation standardisation image quality, e.g. using CDRAD test phantom, constancy testing. The aim this work is evaluate performance an automatic exposure control (AEC) at different sensitivities when used with Fujifilm CR system. Image threshold contrast-detail detectability (TCDD) signal-to-noise ratio squared related dose (SNR2/D), was investigated tube potential values combination. Based on evaluation data, optimum speed modes organ programme settings proposed.
