Conclusion
DQE of all DR systems ranked between 55% and 80%,
being higher in systems using a detector based on direct conversion and newer detector technology.
Generally,
a higher DQE traduced into a higher image quality expressed as IQFinv score.
Target/filter combinations producing spectra of higher mean energy confirmed better performances than conventional Mo/Mo ones.
The innovative photoconductive switching readout exhibited a potential average dose saving of 20% compared to state of the flat panels which use conventional a-Si TFT-matrix readout.
Also slit scanning acquisition showed improved image quality at equal dose compared to standard flat panel detectors.
That technology revealed particularly suited for low dose applications.
At medium doses slit scanning and photoconductive switching readout technologies demonstrated comparable good image quality.
In summary,
it could be confirmed that the technological innovations allow better image quality with lower AGD.
