摘要： A detector and a method for tracking an arrival time of single particles in an ion beam are disclosed, wherein the single particles are provided as a bunch of ions by a synchrotron. Herein, the detector comprises a detector segment comprising a scintillating material, the scintillating material being designated for generating radiation upon passing of a single particle comprised by the bunch of ions through the scintillating material, wherein the scintillating material comprises a plurality of scintillating fibers, the scintillating fibers being provided as a fiber layer, wherein the fiber layer is located perpendicularly with respect to a direction of the incident ion beam; at least one detector element, the detector element being designated for generating a detector signal from the radiation; and at least one evaluation device, the evaluation device being designated for determining information about the single particles from the detector signals provided by the at least one detector element.

摘要： A device (110) and a method for monitoring a treatment of a body part (112) of a patient (114) with a beam (116) comprising particles (118) are disclosed. Herein, the device (110) comprises—a beam delivering unit (120) designated for delivering a beam (116) comprising particles (118) and adjusting a direction (124) of propagation of the beam (116) onto a body part (112) of a patient (114); and—a verification unit (130) designated for verifying a range and a dose delivery of the particles (118) provided by the beam (116) to the body part (112) of the patient (114) by determining information about prompt-gamma radiation (140) generated by an interaction of the particles (118) with the body part (112) of the patient (114) at at least two individual interaction points (150), wherein the verification unit (130) comprises a symmetry axis (149) which is symmetrical with respect to the at least two individual interaction points (150) and which is located perpendicular with respect to the direction (124) of the propagation of the beam (116). The device (110) and the method may be used in the field of particle therapy, specifically for verifying a range and a dose delivery of the particles (118) provided by the beam (116) to the body part (112) of a patient (114), especially towards a tumorous tissue of the patient (114).
