  • Patent number: 11172893
    Abstract: Disclosed herein is a system and method, which utilize primary beam modulation to enable single-scan dual-energy CT (DECT) on a conventional CT scanner. An attenuation sheet with a spatially-varying pattern is placed between the x-ray source and the imaged object. During the CT scan, the modulator selectively hardens the x-ray beam at specific detector locations. Thus, this method simultaneously acquires high and low energy data at each projection angle. High and low energy CT images can then reconstructed from the projections via an iterative CT reconstruction algorithm, which accounts for the spatial modulation of the projected x-rays.

  • Patent number: 11158030
    Abstract: A method for noise reduction in a three-dimensional computed tomography dataset, which is reconstructed from two-dimensional projection images recorded with an x-ray device using different recording geometries, is provided. In a post-processing section following the reconstruction of the computed tomography dataset, to obtain a first intermediate dataset, a first, edge-preserving filter is applied to the reconstructed computed tomography dataset. To obtain a second intermediate dataset, a second, morphological filter is applied to the reconstructed computed tomography dataset. A first weighting dataset weighting edges more strongly is established from a subtraction dataset of the first intermediate dataset and the second intermediate dataset. A noise-reduced result dataset is established as a weighted sum of the first intermediate dataset and the second intermediate dataset.
