Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging
Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.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).

Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 150-155, June 2026.Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that
