Multi-parameter X-ray computed tomography

Patent Number: US8121249
 
Executive Summary:
  • Invention Type: Diagnostic and Device
  • Patent Status: Active
  • Patent Link: https://patents.google.com/patent/US8121249/
  • Research Institute: Virginia Tech
  • Disease Focus: Cancer
  • Basis of Invention: X-ray computed tomography
  • How it works: Systems for x-ray imaging comprising: a) a first collimator-and-detector assembly having a first operable configuration to provide at least one first dataset comprising primary x-ray signals as a majority component of its data capable of being presented as a first image of an object subjected to x-ray imaging; b) a second collimator-and-detector assembly having a second operable configuration or wherein the first collimator-and-detector assembly is adjustable to a second configuration to provide at least one second dataset comprising primary and dark-field x-ray signals as a majority component of its data capable of being presented as a second image of the object; and c) a computer operably coupled with the collimator-and-detector assemblies comprising a computer readable medium embedded with processing means for combining the first dataset and the second dataset to extract the dark-field x-ray signals and produce a target image having higher contrast quality than the images based on the first or second dataset alone
  • Lead Challenge Inventor: Ge Wang
  • Inventors: Ge Wang, Wenxiang Cong
  • Development Stage: Human data
  • Novelty:
    • Acquiring x-ray projection data multiple times with varying collimation is a key feature of obtaining high quality, high contrast images.
  • Clinical Applications:
    • Medical imaging
 
General Description:
This invention involves techniques for extraction of small-angle scattering signals for dark field tomography, while traditional attenuation-based tomography can also be simultaneously performed in cone-beam geometry. This allows for high quality, high contrast images using high-quality x-ray small-angle scattering signals, allowing a significant reduction of the x-ray dose.

Strengths:
  • This scheme can acquire high-quality x-ray small-angle scattering signals, allowing a significant reduction of the x-ray dose
 
Weaknesses:
  • Expensive piece of equipment to replace already existing equipment
