Reduction of Organ Absorbed Dose and Cancer Risk through Optimizing the Use of Projection in Diagnostic X-ray Examination

This study aimed to calculate and compare the estimated organ absorption dose, risk of cancer due exposure, dose received by gonads for women men in radio diagnostic examinations with different projections. Radiographic examination abdomen (with anterior-posterior (AP) posterior-anterior (PA) projections) lumbar vertebrae projection (AP), Right oblique (RPO), Left (LPO)), were performed. Software based on Monte Carlo program has been used absorbed organ, The results showed that PA abdominal resulted lower doses colon wall, liver, pancreas, small intestine wall compared AP projection. a higher than vertebral examination. RPO LPO projections spine produce organs. kidneys, prostate using LPO, bladder, ovaries (women), uterus projected RPO. radiation exposure is 35%-51% reduced projection, 40%-45% ovarian reduction was 54% 11% testicles shown be significant use
