PCXMC - A Monte Carlo program for calculating patient doses in medical x-ray examinations
PCXMC is a computer program for calculating patients' organ doses and effective doses in medical x-ray examinations (radiography and fluoroscopy).
The program calculates the effective dose with both the present tissue weighting factors of ICRP Publication 103 (2007) and the old tissue weighting factors of ICRP Publication 60 (1991). The anatomical data are based on the mathematical hermaphrodite phantom models of Cristy and Eckerman (1987), and the sizes are adjustable to mimic patients of arbitrary weight and height.
Calculated organ doses can be used for the assessment of cancer risk resulting from the radiation exposure. The risk estimates are based on the models of the BEIR VII committee (BEIR 2006).
The program is based on the Monte Carlo method, it is simple to use, and the graphic displays enables visual checking of proper examination conditions.
PCXMC 2.0 is delivered together with a rotation geometry-based user interface (PCXMC20Rotation).
