Analysis of the physical factors influencing portal imaging exit dosimetry using Monte Carlo modeling
As the use of electronic imaging devices (EPIDs) increases, the emphasis which was initially on geometric verification, is shifting to portal exit dosimetry. In this latter concept, a portal dose image obtained during treatment with an EPID is compared with that calculated during treatment planning....
