    • 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).
    • 本发明涉及一种辐射检测器(100; 101; 102; 103; 104; 105; 106),其具有响应于入射辐射(200)的作用产生电磁辐射(202)的闪烁体(120)。 闪烁体(120)在端面(121; 122)之间具有两个相对的端面(121; 122)和侧壁(123)。 此外,辐射检测器还具有位于闪烁体(120)的横向电子壁(123)上并且响应于电磁辐射(202)的作用而产生电子(204)的光电阴极部分(130),所述光电阴极部分 由所述闪烁体(120)产生的微通道板(161; 162)包括多个通道(165),用于将由所述光电阴极部分(130)产生的电子(204)与检测系统(171)相乘 ; 172),用于检测已经通过微通道板(161; 162)倍增的电子(204)。 本发明还涉及一种包括这种类型的辐射探测器(100; 101; 102; 103; 104; 105; 106)的成像系统(110)。
