1. An anti-scatter grid located on a detector comprising a plurality of scintillators, the anti-scatter grid comprising:
a plurality of first grid walls arranged along a first direction, each of the plurality of first grid walls being located above a gap between two adjacent scintillators; and
a plurality of second grid walls arranged along a second direction, wherein
at least two first grid walls of the plurality of first grid walls have different parameters, thereby making a first interspace between any two adjacent first grid walls of the plurality of first grid walls uniform, and
a second interspace between two adjacent second grid walls is non-uniform.
