Electronic Portal Image Device Dosimetry for Volumetric Modulated Arc Therapy

Japanese Journal of Radiological Technology, 2013
Recently electronic portal image devices (EPIDs) have been widely used for quality assurance and dose verification. However there are no reports describing EPID dosimetry for Elekta volumetric modulated arc therapy (VMAT). We have investigated EPID dosimetry during VMAT delivery using a commercial software EPIDose with an Elekta Synergy linac.
