Abstract
A method is for generating X-ray image data of an examination object with reduced calcium blooming. The X-ray image data is based on X-ray projection data acquired with an energy-selective X-ray detector and in respect of at least two energy windows. An embodiment of the method includes determining a calcium content in the X-ray projection data by way of a base material analysis, the calcium content describing the calcium-determined part of the X-ray attenuation caused by the examination object; generating a mixed X-ray projection data record with calcium content suppressed by way of a weighting factor of less than one; and reconstructing the X-ray image data from the mixed projection data record by applying a reconstruction algorithm.
