摘要： The invention relates to a particle beam therapy system (2) comprising an accelerator (4) for making a beam of charged particles available, a beam guiding unit (10, 10a, 10b; 10b*) which supplies the beam to a treatment location (18) starting from the accelerator (4), at least one beam property monitor (28; 28*) arranged along the beam path (6), and a control unit which communicates with the beam property monitor (28; 28*) and the beam guiding unit (10, 10a, 10b; 10b*) and which determines deviations of the actual properties from the desired properties of the beam and transmits control signals for adapting the beam properties to the beam guiding unit (10, 10a, 10b; 10b*), using said deviations. The aim of the invention is to devise a particle beam therapy system which allows a precise guidance of the beam even during a treatment, especially during a particle beam therapy method. This aim is achieved in that the beam property monitor (28; 28*) is arranged on the periphery of the beam perpendicular to the beam path (6) in such a manner that the beam properties are detected due to their direct interaction with particles of the beam in the halo region (36) and/or indirectly by electromagnetic interaction. The invention also relates to a method for guiding a beam of charged particles in a particle beam therapy system.
