Patents Assigned to SHANDONG PROVINCIAL CHEST HOSPITAL
  • Devices, systems and methods utilizing framelet-based iterative maximum-likelihood reconstruction algorithms in spectral CT
    Patent number: 10970886
    Abstract: The disclosed apparatus, systems and methods relate to a framelet-based iterative algorithm for polychromatic CT which can reconstruct two components using a single scan. The algorithm can have various steps including a scaled-gradient descent step of constant or variant step sizes; a non-negativity step; a soft thresholding step; and a color reconstruction step.
