Use of limited sets of dose conversion factors in an interventional radiology procedure

To assess the risk of radiological procedures the quantity effective dose (E) to the patient can be evaluated. Applying dose conversion factors (DCF) to an easily measurable dosimetric quantity, the contribution to E of each view in a diagnostic radiological examination can be obtained. DCF depend on the exposure conditions and are calculated through Monte Carlo (MC) simulation of radiation transport. In fluoroscopy guided interventional procedures DCF for typical views must substitute many similar views for practical reasons. The present study uses the MC code PCXMC to evaluate the influence on E of several excursions in the exposure conditions (authors)
