  • Patent number: 9846131
    Abstract: A motion-based interlock apparatus, system, and method prevent an x-ray source in an x-ray machine from activating if the current relative motion between the x-ray source and an image receptor would compromise the quality of the resulting plain radiograph. The system activates the interlock based on either or both of the velocity and acceleration of the tubehead, as measured by instrumentation corresponding to any of the tubehead, the extension arm, or off board the x-ray machine. The system may preferably compare the measured motion against one or more acceptable motion thresholds. If the measured motion exceeds one or more of the acceptable motion thresholds, exposure may preferably be delayed until the motion of the tubehead subsides. By ensuring that the image is not exposed while the tubehead is moving substantially, the quality of the resultant radiograph is improved.

  • Patent number: 9830685
    Abstract: A method for determining at least one three-dimensional image data record of a target area from two sets of projection images recorded with x-ray spectra using different energy maxima. A first set of projection images is recorded via a first X-ray spectrum and different first projection directions and a second set of projection images via a second X-ray spectrum and different second projection directions which differ at least partially from the first projection directions. A three-dimensional anatomy image data record is reconstructed from the first and the second projection images. A three-dimensional spectral image data record is reconstructed by a weighted combination of a first three-dimensional reconstruction image data record reconstructed from the first projection images, and a second three-dimensional reconstruction image data record reconstructed from the second projection images. The anatomy image data record and the spectral image data record are displayed.

  • Patent number: 9823203
    Abstract: Systems for x-ray diffraction/scattering measurements having greater x-ray flux and x-ray flux density are disclosed. These are useful for applications such as material structural analysis and crystallography. The higher flux is achieved by using designs for x-ray targets comprising a number of microstructures of one or more selected x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray flux. The high brightness/high flux source may then be coupled to an x-ray reflecting optical system, which can focus the high flux x-rays to a spots that can be as small as one micron, leading to high flux density, and used to illuminate materials for the analysis based on their scattering/diffractive effects.

  • Patent number: 9782142
    Abstract: In the X-ray CT system according to an embodiment, a control means displaces and images imaging regions in the subject by controlling a top board driver and an imaging means such that the X-rays are projected onto the subject every time a top board is moved by a predetermined transfer amount. An acquiring means acquires projection data of the respective imaging regions. A reconstruction means, based on the projection data, reconstructs tomographic images for each predetermined size of a reconstruction region. In the scan control mode, the control means outputs the transfer amount corresponding to this mode to the top board driver. In the reconstruction control mode, the control means outputs the size of the reconstruction region corresponding to this mode to the reconstruction means.
