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 conversion system (160) located on the lateral wall (123) of the scintillator (120), said system comprising a plurality of channels (165). Each channel (165) has a photocathode section (130; 131; 132) for generating electrons (204) in response to the action of electromagnetic radiation (202) that is generated by the scintillator (120), said electrons being multipliable by impact processes in the channels (165). A detection system (170) for detecting electrons (204) that have been multiplied in the channels (165) of the conversion system (160) is also provided. The invention also relates to an imaging system (110) comprising a radiation detector of this type (100; 101; 102; 103; 104; 105; 106).
