摘要： Present invention relates to devices and methods for determining a calcium content by analyzing cardiac spectral CT data. CT projection data (9), obtainable by scanning a cardiac region of a subject using a spectral CT scanning unit, is modelled (12) by applying a material decomposition algorithm to the projection data to provide a calcium-specific component. Tomographic reconstructions (13) of the projection data, to provide a first 3D image (8), and of the calcium-specific component, to provide a second 3D image (6), are performed. The first 3D image (8) is segmented (14) to provide an image mask (5) corresponding to a cardiovascular structure of interest, a part of the second 3D image (6) is selected (15) based on the image mask (5), and a calcium content is calculated (16) in the cardiovascular structure of interest based on the selected part of the second 3D image (6).

摘要： The present invention relates to computer tomography X-ray imaging. In order to provide further improved data for the reconstruction, a system (10) for computer tomography X-ray imaging is provided. The system comprises a data interface (12) and a processing unit (14). The data interface is configured to provide at least first and second CT X-ray radiation projection data for at least a first and second X-ray energy range, which ranges are different from each other. The processing unit is configured to determine a correction for slice normalization, and to apply an equal slice normalization for the first and the second CT X-ray projection data and thereby generating prepared first and second CT X-ray projection data. For the correction, the equal slice normalization is based on measured data of outer detector elements. Further, the data interface is configured to provide the prepared first and second CT X-ray projection data for further processing. In an example, the system further comprises a computer tomography X-ray imaging acquisition arrangement (20) with an X-ray source (22) configured to generate an X-ray beam, and an X-ray detector (26) configured as an energy discriminating X-ray detector to simultaneously provide X-ray radiation projection data for at least two different X-ray energy ranges separately. The computer tomography X-ray imaging acquisition arrangement is configured to acquire at least the first and second CT X-ray projection data of a region of interest of an object for the at least first and second X-ray energy range.
