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 (6, 8), having vertical deflection means (13) and horizontal deflection means (14) for the vertical and horizontal deflection of a treatment beam (11) perpendicular to its beam direction, with the result that the treatment beam (11) is deflected by the grid scanner device to an isocentre (10) of the irradiation site, and a specific area surrounding the isocentre (10) 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.
