Objective:To evaluate the positioning accuracy of the Topslane body localization frame.Methods:31 cases of chest tumor were immobilized using the Topslane body localization frame.Fiducial markers were deliberately placed on each patient′s skin.CT images were transferred to TPS via DICOM 3.0.Calculated and measured coordinates of markers were compared.Results:The positioning accuracy of the Topslane body localization was found to be within±2·!mm.Conclusion:The Topslane body localization frame has good mechanical property.It is simple for use in patient immobilization and setup verification.
