Calculation of radiation dose to the lens of the eye using Monte Carlo simulation

The radiation dose to the lens of the eye of patients undergoing diagnostic and interventional radiological procedures of the lacrimal drainage system has been calculated using a Monte Carlo technique. The technique has also been suggested for the retrospective estimation of the lens dose; when appl ied to individual patients, good correlation is obtained. In such study, da ta is required for image acquisition frame numbers and fluoro on-time, mean exposure values for these parameters, and the ratio of lens-to-air dose (v iz. the head factor, HF) derived for a standard adult head.
