Cross-hatched, focused, x-ray scatter reduction grid fabricated by lamination technique
An X-ray scatter reduction grid includes a first layer having a plurality of cells. The cells have a perimeter formed of an X-ray absorbing material. The shape of the perimeters can vary, but a polygonal shape is preferred. The grid can also include other layers, each with their own cells. The cells of the subsequent other layers are larger than and offset from the cells of the prior layer. The increased size of the cells allows a primary ray passing through the center of a first layer cell to also pass through the center of a subsequent layer cell. This allows for a maximum of primary ray passthrough and a maximum of scatter absorption.
