发明名称 Method and device for segmenting at least one substance in an x-ray image
摘要 A method is disclosed for generating CT displays in x-ray computed tomography with contrast medium support, the blooming effect being reduced by decomposing an object into three material components when scanning the object with two different energy spectra, and determining a first component and determining the material thickness thereof by segmentation. Subsequently, in at least one embodiment, the two other material components and their material thicknesses are determined on the basis of the measured attenuation values of the two spectra for each beam, and virtual absorption data with virtual absorption coefficients are constructed for the individual material components from the material strengths thus known for the different material components, and are used to reconstruct the CT display.
