Abstract
The invention relates to a method of checking the beam guidance 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 a specific area surrounding the isocentre ( ) is scanned, wherein redundancy means are used for a redundant termination of extraction and their functionality is checked and checking of the ability of beam guidance dipoles in the beam guidance to connect and disconnect is carried out.
