  • Patent number: 10468230
    Abstract: A system and method for imaging a sample having a complex structure (such as an integrated circuit) implements two modes of operation utilizing a common electron beam generator that produces an electron beam within a chamber. In the first mode, the electron beam interacts directly with the sample, and backscattered electrons, secondary electrons, and backward propagating fluorescent X-rays are measured. In the second mode, the electron beam interrogates the sample via X-rays generated by the electron beam within a target that is positioned between the electron beam generator and the sample. Transmitted X-rays are measured by a detector within the vacuum chamber. The sample is placed on a movable platform to precisely position the sample with respect to the electron beam. Interferometric and/or capacitive sensors are used to measure the position of the sample and movable platform to provide high accuracy metadata for performing high resolution three-dimensional sample reconstruction.

  • Patent number: 9390881
    Abstract: A compact source for high brightness x-ray generation is disclosed. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sub-sources, or through the use of x-ray targets that comprise microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and/or higher energy electrons, leading to greater x-ray brightness. Some embodiments of the invention comprise x-ray optical elements placed between sub-sources of x-rays. These x-ray optical elements may form images of one or more x-ray sub-sources in alignment with other x-ray sub-sources, and may enhance the linear accumulation that can be achieved.

  • Patent number: 8989346
    Abstract: From radiation images obtained by driving radiation tube with a plurality of tube voltages, including a normal tube voltage, a density gradient with respect to at least two sections of a reference substance having different radiation transmission characteristics is obtained for each of the plurality of tube voltages prior to obtaining a bone mineral density. If a radiation image captured for obtaining a bone mineral density is determined to have been captured under a tube voltage other than the normal tube voltage, an image signal representing the image and/or a bone mineral density analysis result is corrected so as to correspond to that which should have been obtained if the image had been captured under the normal tube voltage based on the relationship between the density gradient in the image and the density gradient in the radiation image captured under the normal tube voltage.

  • Patent number: 8853584
    Abstract: Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.
