Materials/Methods:
This is a multi‐center study. The same CT image set and associated structures were transferred via DICOM‐RT to each center for planning. Each institution was asked to generate the optimal plan based on anatomy, technical and clinical considerations as if the patient was going to be treated. To assure the fairness of the comparison, each center was not given any information in regard to how other modalities are doing for that patient. Data was collected and analyzed at our institute. Three test patients have been analyzed. The indices used in the analysis include dose gradient outside the target, target coverage, dose conformity, dose homogeneity, and dose to organs at risk.
