1. A system comprising:
a radiation source;
a detector comprising a plurality of detector cells;
a first grid located between the radiation source and the detector, the first grid comprising a plurality of first radiation transmitting sections; and
a second grid located between the first grid and the detector, the second grid comprising a plurality of second radiation transmitting sections;
wherein
an extending direction of at least one of the plurality of first radiation transmitting sections is perpendicular to an extending direction of at least one of the plurality of second radiation transmitting sections; and
at least one of the plurality of detector cells comprises an active area receiving radiation from the radiation source that passes through at least one of the plurality of first radiation transmitting sections and/or at least one of the plurality of second radiation transmitting sections.
