dose reduction in patients undergoing Chest Imaging digital amorphous silicon flat panel detector radiography versus conventional film screen radiography and phosphor based computed radiography
American Journal of Roentgenology, 2003Co-Authors: Klaus Ache, A. De Hauwere, Koenraad Verstraete, Pete Smeets, Kris Onnarens, Hube ThierensAbstract:OBJECTIVE. We sought to compare the radiation dose delivered to patients undergoing clinical Chest Imaging on a full-field digital amorphous silicon flat-panel detector radiography system with the doses delivered by a state-of-the-art conventional film-screen radiography system and a storage phosphor-based computed radiography system. Image quality was evaluated to ensure that the potential reduction in radiation dose did not result in decreased image acuity.SUBJECTS AND METHODS. Three groups of 100 patients each were examined using the amorphous silicon flat-panel detector, film-screen, or computed radiography systems. All patient groups were matched for body mass index, sex, and age. To measure the entrance skin dose, we attached 24 calibrated thermoluminescent dosimeters to every patient. The calculation of the effective dose, which represents the risk of late radiation-induced effects, was based on measurements on an anthropomorphic phantom. Image quality of all three systems was evaluated by five exp...

digital radiography versus conventional radiography in Chest Imaging diagnostic performance of a large area silicon flat panel detector in a clinical ct controlled study
American Journal of Roentgenology, 2000Co-Authors: Marietta Garme, Svenja P Hennigs, Hors Jage, Felicitas Schrick, Thomas Van De Loo, Andreas Jacobs, Axel Hanusch, Andreas Christma, Klaus MathiasAbstract:OBJECTIVE. The objective of this study was to compare the diagnostic performance of a digital large-area silicon flat-panel detector with that of a conventional screen-film system in clinical Chest Imaging using abnormal findings documented by CT as the reference standard.SUBJECTS AND METHODS. Eighty patients (46 men and 34 women; age range, 18-91 years; mean age, 63 years) who underwent CT of the Chest were examined with the new digital radiography system, which is based on a 43 × 43 cm silicon flat-panel detector, and with a conventional screen-film system, which is used routinely in clinical practice. Posteroanterior and lateral radiographs were obtained. Four radiologists analyzed the digital and conventional images separately for Chest abnormalities and rated the images using a five-level scale of confidence; CT was used as the reference standard. Diagnostic value was assessed using receiver operating characteristic curves for each abnormality.RESULTS. No significant differences were found between th...
