Abstract

The invention relates to a detection apparatus for detecting radiation. The detection apparatus comprises a GOS material (20) for generating scintillation light depending on the detected radiation (25), an optical filter (24) for reducing the intensity of a part of the scintillation light having a wavelength being larger than 650 nm, and a detection unit (21) for detecting the filtered scintillation light. Because of the filtering procedure relatively slow components, i.e. components corresponding to a relatively large decay time, of the scintillation light weakly constribute to the detection process or are not detected at all by the detection unit, thereby increasing the temporal resolution of the detection apparatus. The resulting fast detection apparatus can be suitable for kVp-switching computed tomography systems.
