Abstract

The invention relates to a method of checking emergency shutdown of an ion beam therapy system which comprises a raster scanning device arranged in a beam guidance system and having vertical deflection means and horizontal deflection means for the vertical and horizontal deflection of a treatment beam at right angles to its beam direction, so that the treatment beam is deflected by the raster scanning device onto an isocenter of the irradiation station and scans a specific area surrounding the isocenter, a check of emergency shutdown being carried out.
