  • Patent number: 11340364
    Abstract: A method for providing an item of conversion information describing an allocation rule of at least one physical property value of a material in a voxel relating to an image value of the voxel in a three-dimensional image dataset recorded with an X-ray apparatus is provided. By scanning a phantom including at least one calibration material in the X-ray apparatus, a calibration database that is used for determining the allocation rule is determined. The image dataset is recorded with a receiving spectrum geared to an X-ray detector of the X-ray apparatus. The receiving spectrum is described by at least one spectral parameter. For determining the allocation rule dependent upon the spectral parameter, calibration data derived from the measured calibration dataset describing different receiving spectra is used.

  • Patent number: 10825208
    Abstract: An adaptive method for generating CT image data is described. In the method, projection measurement data of an examination region of an examination object is acquired. Furthermore, uncorrected image data of the examination region is generated. Artifact-affected subregions of the examination region are determined on the basis of at least one part of the uncorrected image data. An artifact-reduced image reconstruction is carried out in the artifact-affected subregions of the examination region. Only artifact-reduced subimage data of the artifact-affected subregions is generated. Finally, artifact-reduced image data of the entire examination region is generated by combining at least one part of the uncorrected image data and the artifact-reduced subimage data. A reconstruction device is also described. Moreover, a computed tomography system is described.
