The Electronic Portal Imaging Device (EPID) provides localization quality images and computer-aided analysis, which should in principal, replace portal film imaging. Modern EPIDs deliver superior image quality and an array of analysis tools that improve clinical decision making. It has been demonstrated that the EPID can be a powerful tool in the reduction of treatment setup errors and the qual...

Purpose: Kilovoltage cone-beam computed tomography (CBCT) has been developed to provide accurate soft-tissue and bony setup information. We evaluated clinical CBCT setup data and compared CBCT measurements with electronic portal imaging device (EPID) images. Material and Methods: The setup error for CBCT scans at the treatment unit relative to the planning CT was measured for 62 patients (524 s...

Abstract Introduction: In vivo dosimetry verification is currently a necessity in radiotherapy centres Europe countries as one of the tools for patient-specific QA, and now its demand rising developed countries, such Malaysia. The aim this study to characterize commercial EPID-based implementation treatment Materials Methods: work, sensitivity performance commercially available system, EPIgray®...
