Patent ID: 7791033

Claim:
A system for three-dimensional imaging of an object prepared with radio-labeled substances, wherein said system comprises in-line x-ray optics arranged in combination with an X-ray detector to detect ionizing radiation from said radio-labeled substances, wherein said in-line x-ray optics are built from a number of flat pieces of lenses, each one of said flat pieces of lenses including a plurality of lenses manufactured side-by-side on a wafer, each lens comprising a plurality of prisms, wherein several wafers are stacked to form a lens arrangement, and wherein said x-ray detector includes a number of x-ray detecting units arranged to cover an area of an image plane of the in-line x-ray optics, and wherein said in-line x-ray optics are arranged for focusing on a position where the object is to be placed and said x-ray detector is positioned sufficiently close to or at an image plane of said x-ray optics in order to map ionizing radiation from said radio-labeled substances onto said x-ray detector for three-dimensional imaging of said object, and said in-line x-ray optics is designed such that an x-ray hitting the detector will not come from more than one lens.
