| 摘要 |
A detector arrangement of an imaging system detector detecting ionizing radiation includes a detector carrier, a plurality of detector modules attached to the detector carrier, and a collimator disposed in the radiation direction in front of the detector modules which are disposed on the incident radiation measurement side. In at least one embodiment, at least one air gap is included for conveying cooling air is disposed between the collimator and the measurement sensors of the detector modules. A method is also disclosed for cooling a detector arrangement of a detector rotating around a system axis with a plurality of measurement sensors disposed next to one another and a collimator arranged in the radiation direction in front of the measurement sensors, wherein cooling air is conveyed in or against the system axis direction between the collimator and the measurement sensors which directly cools the surface of the measurement sensors.
