Webb27 apr. 2024 · The x-ray tube angle was also found to have a significant effect on patient dose. Due to staff dose being highly correlated with patient dose, it was difficult to observe any association between staff dose and CFA imaging mode, but this does not discount a potential increase in occupational dose due to the use of higher dose imaging modes.
