Abstract
An apparatus (112) provides for tuning of an effective focal spot size of a radiation source. The apparatus may comprise a plurality of inter-channel structures (214) defining a plurality of channels (216) passing through the apparatus from a first surface (218) to a second surface (220). The inter-channel structures comprise a first substance and the channels contains a second substance. The first substance attenuates radiation more than the second substance. The inter-channel structures may define the channels such that lines passing through the channels converge at a location on or near the surface of a focal spot (212).
