Direct dose to water dosimetry for pretreatment IMRT verification using a modified EPID

, 2011
Purpose: Electronic portal imaging devices (EPIDs) are high resolution systems that produce electronic dose maps with minimal time required for equipment setup, and therefore potentially present a time-saving alternative for intensity modulated ...
