Abstract
A method for the verification of the calculated radiation dose of an ion beam therapy system that comprises a grid scanner device, arranged in a beam guidance system ( ), having vertical deflection means ( ) and horizontal deflection means ( ) for the vertical and horizontal deflection of a treatment beam ( ) perpendicular to its beam direction, with the result that the treatment beam ( ) is deflected by the grid scanner device to an isocentre ( ) of the irradiation site and scans a specific area surrounding the isocentre ( ), irradiation being carried out on the basis of automatically calculated radiation dose data. The accuracy of the calculation of the radiation dose data is verified by using a phantom, a discrepancy between the radiation dose calculated for the at least one measurement point of the phantom and a radiation dose measured for the at least one measurement point being determined and evaluated.
