Abstract

The invention relates to a radiation detector (100; 101; 102; 103; 104; 105; 106), having a scintillator (120) for generating electromagnetic radiation (202) in response to the action of incident radiation (200). The scintillator (120) has two opposing end faces (121; 122) and a lateral wall (123) between the end faces (121; 122). The radiation detector has, in addition, a photocathode section (130) that is located on the lateral electrons wall (123) of the scintillator (120) and that generates electrons (204) in response to the action of electromagnetic radiation (202) that is generated by the scintillator (120), a microchannel plate (161; 162) comprising a plurality of channels (165), for multiplying the electrons (204) that have been generated by the photocathode section (130) and a detection system (171; 172) for detecting the electrons (204) that have been multiplied by means of the microchannel plate (161; 162). The invention also relates to an imaging system (110) comprising a radiation detector of this type (100; 101; 102; 103; 104; 105; 106).
