Organ Dose Calculation in Medical X Ray Examinations by the Program PCXMC

Abstract

PCXMC is a PC-based Monte Carlo program for calculating patients' organ doses and the effective dose in medical X ray examinations. It uses mathematical phantom models, and can be used to compute the doses in 25 organs of patients of different ages and sizes in freely adjustable X ray projections and other examination conditions of projection radiography and fluoroscopy. The organ doses calculated with PCXMC agree well with the doses calculated by the National Radiological Protection Board for common X ray examinations and with the doses calculated by Stern et al for cineangiographic examinations of coronary arteries.
