Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a specialized mounting structure for interferometric gratings used in differential phase contrast and dark-field X-ray imaging. The invention provides a curved mounting surface with precise apertures (such as slits) that allow gratings to be securely positioned and aligned with detector pixels, thereby improving image quality and maintaining the curvature necessary for optimal interferometric imaging. The structure is particularly suited for compact imaging systems such as mammography, ensuring high visibility and undisturbed X-ray passage during scanning operations.

Use CasesContent extracted from patent full text and abstract with AI.

  • Mammography machines that utilize differential phase contrast and dark-field X-ray imaging for better soft tissue visualization.
  • General medical imaging systems (including CT, dental, or orthopedic) that use interferometric imaging techniques.
  • Industrial non-destructive material inspection relying on phase contrast or scatter imaging to detect structural anomalies.
  • Research instruments for advanced X-ray imaging and analysis in materials science.
  • Development of compact, high-resolution X-ray imaging devices where space constraints and image clarity are critical.

BenefitsContent extracted from patent full text and abstract with AI.

  • Enables robust, precise, and stable mounting of curved gratings, preserving optimal alignment and curvature for high-quality imaging.
  • Minimizes deformation and sagging of gratings, reducing artifacts or image quality loss due to grating movement or misalignment.
  • Facilitates undisturbed passage of X-rays through the mounting structure, improving imaging signal robustness and fidelity.
  • Aperture patterns are designed for alignment with detector pixels, supporting efficient imaging with minimal loss of data or signal.
  • Supports easy installation and adjustment of gratings, accommodating manufacturing tolerances and different grating geometries.
  • Adaptable to different imaging geometries and detector layouts, increasing flexibility for manufacturers and system integrators.
  • Enhances the reliability and robustness of phase-contrast and dark-field imaging, enabling broader deployment in clinical and industrial settings.
