<p>A shielding grid (44) constructed of a radiation absorbing material (46, 48) for use with an array of discreet, non-contiguous radiation sensors to protect such sensors from scattered radiation. The sensors each have a radiation sensitive area (11) with a width (Ws) and a length (W1). In designing the grid a prototile having a prototile width and a prototile length is developed. The prototile width is equal to the radiation sensitive area width divided by an integer, and the prototile length is also equal to the radiation sensitive area length divided by an integer. The prototile contains a motif contained solely within the prototile that forms a pattern when a plurality of prototiles sufficient to cover the array of discreet detector are arrayed contiguously. The grid is constructed with the radiation absorbing material in this pattern.</p> |
