Development and testing of an improved dosimetry system using a backscatter shielded electronic portal imaging device.

Abstract

PURPOSE To investigate the properties of a modified backscatter shielded electronic portal imaging device (BSS-EPID) and to develop a dose model to convert BSS-EPID images to dose in water as part of an improved system for dosimetry using EPIDs. METHODS The effectiveness of the shielding of the BSS-EPID was studied by comparing images measured with the… (More)
