ANALISIS DOSIS EFEKTIF PADA PASIEN PEMERIKSAAN ABDOMEN AP DENGAN CALDOSE_X VERSI 5.0

This study evaluates radiation dose exposure during diagnostic radiology procedures using X-rays and their potential risks, including cancer, to optimize radiation safety through the CALDose_X software that calculates the absorbed organ dose, effective dose, and cancer risk, according to the lowest possible achievable (ALARA) principle. This study used a quantitative experimental design to evaluate the impact of filter thickness variations on Entrance Surface Air Kerma (ESAK) and effective dose by analyzing data from 54 patients undergoing AP Abdominal X-ray examinations. The results showed that the effective dose to the abdominal organs varied with exposure factors and Focus to Detector Distance (FDD), where the colon wall had the highest sensitivity with doses ranging from 0.030 mSv to 0.126 mSv, followed by the stomach and pancreas. Increasing kV, mAs, and FDD increased the effective dose, emphasizing the importance of careful dose management. This study concluded that exposure factors and FDD affect the effective dose received by the abdominal organs, with recommendations to monitor patient doses, revise national diagnostic reference levels, and establish standard protocols with health authorities.
