  • Patent number: 9304605
    Abstract: An information management system is intended for management of digitally represented information which is associated with absolute positions on an imaginary surface (200). The imaginary surface (200) contains at least two regions (201-208), each of which is dedicated to predetermined management of the digitally represented information. In the system the management of the digitally represented information is carried out on the basis of the region affiliation of the absolute positions associated with the information. The system is suitably based on use of a position-coding pattern which defines the imaginary surface (200) and which in parts is applicable on different bases. The system makes possible both digital recording of information and control of how the information thus recorded is to be managed. A database, a method for management of information, a method for compiling a pattern layout, a product and use are also described.

  • Patent number: 9025883
    Abstract: What is disclosed is a system and method which reconstructs an N-pixel image of a scene such that Q pixel locations associated with identified regions of interest in a scene have a higher image quality when rendered relative to other pixels in the image. Acquisition and adaptive-quality compression are performed simultaneously by semi-synchronously or asynchronously temporally modulating an ordered set of sampling functions used to spatially modulate a pattern of light. The teachings hereof improve compression efficiency of a compressed sensing framework while improving encoding efficiency with respect to traditional compressed sensing techniques.

  • Patent number: 7778386
    Abstract: Disclosed are embodiments of methods for reconstructing x-ray projection data (e.g., one or more sinograms) acquired using a multi-source, inverse-geometry computed tomography (“IGCT”) scanner. One embodiment of a first method processes an IGCT sinogram by rebinning first in “z” and then in “xy,” with feathering applied during the “xy” rebinning. This produces an equivalent of a multi-axial 3rd generation sinogram, which may be further processed using a parallel derivative and/or Hilbert transform. A TOM-window (with feathering) technique and a combines backprojection technique may also be applied to produce a reconstructed volume. An embodiment of a second method processes an IGCT sinogram using a parallel derivative and/or redundancy weighting. The second method may also use signum weighting, TOM-windowing (with feathering), backprojection, and a Hilbert Inversion to produce another reconstructed volume.
