| 摘要 |
The invention relates to a radiation detector (100) comprising a scintillator group with for example two scintillator elements (120a, 120b) for converting incident primary photons (X, X') into secondary photons (?, ?') according to a characteristic emission spectrum. Moreover, the detector comprises at least two photodetectors (120a, 120b) for converting said secondary photons into electrical signals, wherein said photodetectors have different absorption spectra and can be read out separately. According to a preferred embodiment of the invention, the photodetectors are organic photodetectors (120a, 120b). The scintillator elements (120a, 120b) and the photodetectors are preferably arranged in a stack one behind the other. Due to the at least two photodetectors (120a, 120b), additional information about incident primary radiation (X, X') can be collected. |
