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.

Abstract: A method and a system are for calculating an output from a tomographic scrollable image stack, including a large number of generated sectional images of a tissue to be examined. In this context, a tomographic scrollable image stack is received. An output for a display is calculated. The output includes a primary image that is intended for representing the received image stack, and the output includes a secondary image with additional information. The secondary image is displayed overlaid on the primary image once an unhide signal or hide signal is received. In this context, a reference may be provided between the additional information of the secondary image and the slice of tissue for examination that is shown in the sectional image of the image stack.
