  • Method of operating an ion beam therapy system with monitoring of beam position
    Patent number: 6600164
    Abstract: A method for the operation 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 scans a specific area surrounding the isocentre (10). For monitoring the operational stability and operational safety of the therapy system, the beam position of the treatment beam (11) in the region of the isocentre (10) is monitored and evaluated, intervention in the ion beam therapy system being carried out if the evaluation of the beam position shows a departure, from a predetermined desired value, that exceeds a specific tolerance value based on a required half-value width of the beam profile.

  • Method for monitoring an emergency switch-off of an ion-beam therapy system
    Patent number: 6597005
    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.

  • Apparatus and method for controlling a radiation device
    Patent number: 6509573
    Abstract: An arrangement and a method for controlling a radiation device, in particular for heavy ion therapy, are described. The arrangement comprises a chain of circuit modules (11-17), each circuit module (11-17) having a separate communication connection to a preceding circuit module and a separate communication connection to a following circuit module. In the method for controlling the radiation device by means of control modules (11-17) arranged in a chain, each control module (11-17) communicates separately with a preceding control module and separately with a following control module.
