Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, EarlyView.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

The Importance of Patient Positioning in Radiography When Utilising Automatic Exposure Control

Journal of Medical Radiation Sciences, EarlyView.
This study highlights the impact of inaccurate patient positioning on dose and image quality when utilising the automatic exposure control (AEC) for radiographic examinations. While the AEC serves to optimise radiation dose to patients, the results here demonstrate that poor positioning can lead to significant dose implications for patients.

Image Reject Patterns in Computed Radiography: Insights From a Ghanaian Radiology Department

Journal of Medical Radiation Sciences, EarlyView.
This study examined image rejection patterns in a computed radiography system at a tertiary hospital in Ghana. An overall reject rate of 16.5% was observed, exceeding recommended thresholds, with anatomical cut‐off and positioning errors being the most common causes.
