Hoberg4, F. Wanninger5, L. Verstreepen6, F. G. Mueck7, D. Maxien8, F. Fischer9, O. Peschel9 & S. Wirth10 In recent phantom studies low-contrast detectability was shown to be independent from variations in tube voltage in digital radiography (DR) systems...
The variation of the number of observable discs between simulated and real images shows a good agreement (less than two discs difference) for high contrast and low contrast for 50%, 32% and 12.5% dose levels. From the visual validation of the senior radiologists on both CIRS phantoms, there...
ACR standards for the performance of adult chest radiography were applied: 117 kVp; 1-12 mAs; grid: 70 lines, 8:1. Parameters for NIP: 90 kVp; 0.5-6 mAs; grid: 70 lines, 8:1. A modified MUSICA1 image processing was used for both modalities: MUSI contrast: 3, edge contrast: 0, ...
A method and system for processing a radiography image derived from an X-ray radiation passing through an object. The method includes acts of estimating, based on the radiography image, a scatter signal present in said radiography image; calculating, based on the estimated scatter signal, a ...

A method () for processing a radiography image derived from an X-ray radiation passing through an object, and a radiography system () for performing such method. The method () comprises a step () of estimating, based on the radiography image, a scatter signal present in said radiography ...
Previously, we compared the radiation dose and image quality measured by using a contrast detail test object [1]. The results confirmed that radiation doses were lower for the LDSS system than for two conventional DR systems but that both modalities yielded equally adequate image quality. The e...
