X ray imaging system
Abstract
The invention provides a method and apparatus for focusing and imaging x-rays. An opaque sphere is used as a diffractive imaging element to diffract x-rays from an object. The divergent x-ray wavefronts are then transformed into convergent wavefronts. The convergent wavefronts are brought into focus to form an image of the object. The new image has a large depth of field.
