    摘要： A method and an x-ray computed tomography system are disclosed for visualizing at least two different types of cardiac tissue, such as normally perfused tissue, hypoperfused tissue and scarred tissue. In at least one embodiment, this is done by use of an imaging tomographic recording technique with the aid of x-ray radiation, wherein at least one cardiac region of a patient is scanned by x-ray radiation which passes through a first grating for the passing-through x-ray radiation, designed as an absorption grating, prior to reaching the patient, and at least the locally caused phase-shifts of the x-ray radiation in the cardiac region are also made detectable by using a second grating for the passing-through x-ray radiation, designed as a phase grating, downstream of the patient in the emission direction, and the spatial distribution of these shifts is measured and reconstructed, wherein an average specific phase-shift value is assigned to each spatial unit, wherein each of the abovementioned tissue types are assigned to a region of a typical specific phase-shift value and at least one region assigned to a tissue type is optically highlighted in a view of the cardiac region.

    摘要： A method is disclosed for marking and visualizing an implant by use of an x-ray phase-contrast tomography examination. Further, an implant is also disclosed. In at least one embodiment, implants are used with specific characteristics which are as unambiguous as possible with regard to the phase shift generated by the implants in a phase-contrast tomography examination. In at least one embodiment, these specific characteristics can include the typical self-generated specific phase shift, typical differences in the specific phase-shift values, or typical spatial structures of materials with well-defined phase-shift values.

    摘要： A method and an x-ray system are disclosed for detecting and localizing a metabolic marker. In at least one embodiment, the method includes creating at least one absorption x-ray view of a patient or of a first region of a patient; creating at least one phase-contrast x-ray view of the patient or of a second region of the patient, with a quasi-coherent x-ray radiation being generated for the phase-contrast measurement with the aid of an x-ray grating arranged between the x-ray source and the patient, and the spatially dependent phase shift of the x-ray radiation in the patient being made visible with the aid of at least one grating between the patient and a detector; superposing the at least one absorption x-ray view and the at least one phase-contrast x-ray view; wherein orientation based on anatomical features is carried out with the aid of the at least one absorption x-ray view, and a spatial distribution of the metabolic marker present in the body of the patient is determined by the at least one phase-contrast x-ray view.
