The invention concerns a detector arrangement for detection of radiation, in particular particle radiation or electromagnetic radiation, with a semi-conductor detector with several pixels for detection of the radiation. It is proposed that the individual pixels each have a first subpixel () and a second subpixel (). The semi-conductor detector can be switched between a first collection state, in which the first subpixel () is sensitive and the second subpixel () is insensitive so that radiation-generated signal charge carriers are substantially collected only in the first subpixel (), and a second collection state in which the second subpixel () is sensitive and the first subpixel () is insensitive so that the radiation-generated signal charge carriers are collected substantially only in the second subpixel (). The invention furthermore concerns a corresponding operating method and detector arrangements based on the same concept with a higher number of subpixels per pixel.
