1. A detection apparatus for a CT system, comprising:
a high-energy detector assembly comprising a plurality of rows of high-energy detectors arranged along a predetermined trajectory; and
a low-energy detector assembly comprising a plurality of rows of low-energy detectors arranged at intervals along the predetermined trajectory, the low-energy detector assembly and the high-energy detector assembly being disposed in a stack;
wherein a number of rows of the low-energy detectors is smaller than a number of rows of the high-energy detectors; and
each row of the low-energy detectors covers a row of the high-energy detectors.
