Abstract:
1. An x-ray refractive element formed of a body of low-Z material having a first end adapted to receive x-rays emitted from an x-ray source and a second end from which the x-rays received at the first end emerge, said x-ray refractive element comprising: a first row of substantially identical prisms disposed between said first end and said second end along a first direction, and a second row of substantially identical prisms disposed between said first and second ends along the first direction, each of said prisms of said first row and each of said prisms of said second row being of a substantially triangular shape having two side portions and one base portion, said first row of substantially identical prisms being arranged on top of said second row of substantially identical prisms in a second direction perpendicular to the first direction such that a base portion of a given prism in said first row faces an intersection point of said side portions of a given prism in said second row.
