20100158196 | Radiation beam blocker with non-cylindrical through-hole causing reduced geometric unsharpness in radiographic image, and method for the preparation thereof - An aperture plate, consisting of a beam blocker with a through-hole in the micrometer diameter range, is positioned in the primary radiation beam between the radiation initiation point and the specimen. The micro-hole extends along the thickness of the beam blocker, is non-cylindrical with a narrow center region, and allows photons emitted by any given sub-region of the initiation point to pass through the beam blocker, if those photons propagate along a specific vector. Therefore, any specimen feature of interest can only be exposed by photons from a sub-region of the initiation point. This results in an effective radiation initiation point size reduction, and allows for examinations of large or dense objects with hard x-rays or high intensity gamma radiation, while at the same time minimizing geometric unsharpness in the resulting radiographic images. The micro-hole configuration can be controlled by stacking and securing multiple plates with various micro-hole diameters. | 06-24-2010 |
