1. A matrix of detectors configured to be used in a system for inspecting cargo using inspection radiation, the matrix comprising a plurality of columns of detector modules,
the detector modules of each column extending along a substantially longitudinal direction,
each detector module comprising an inspection surface configured to receive the inspection radiation, and
the plurality of columns of detector modules being adjacent to each other in a lateral direction substantially perpendicular to the longitudinal direction and substantially parallel to the surfaces of the detector modules,
wherein the plurality of columns of detector modules comprises at least two columns of detector modules being offset with respect to each other in an in-depth direction substantially perpendicular to both the lateral direction and the longitudinal direction, wherein an offset δ between the inspection surfaces of one column and the inspection surfaces of another, offset column is such that:
0<δ≤5D,
wherein D is a dimension of the detector modules in the in-depth direction.
