1. A detector apparatus, comprising:
a detecting module configured to detect radiation rays emitted from a subject and generate electrical signals in response to detection of radiation rays, wherein
the detecting module includes a plurality of detecting cells arranged along an axial direction of a scanner including the detector apparatus, the axial direction being perpendicular to a circumferential direction of the scanner, each of the plurality of detecting cells includes a detecting unit and a first electronics unit, the detecting unit is configured to generate visible light signals in response to detection of the radiation rays, and the first electronics unit is configured to convert the visible light signals into electrical signals, at least one of the plurality of detecting cells is detachable from the detecting module;
an electronics module configured to process the electrical signals generated by the detecting module; and
a cooling assembly configured to cool the detecting module and the electronics module, the cooling assembly including a first layer and a second layer, wherein
the first layer is thermally connected with the detecting module, and the second layer is thermally connected with the electronics module, each of the plurality of detecting cells is connected with a first cooling plate of the cooling assembly detachably via one or more connecting mechanisms.
