| abstract |
The invention relates to a method for providing an evaluation data set (BD1) from a first medical three-dimensional computer tomography data set (CD1), comprising: - Reconstructing (51) the first three-dimensional computed tomography data set (CD1) from a plurality of two-dimensional projection X-ray images (1) of different recording geometries recorded by a medical X-ray device (37) of an examination subject (31), - Provision of an artifact-reduced image data set (AD1), wherein the provision comprises an application of an algorithm for reducing artifacts (52) to the first computed tomography data set (CD1), - Identification of, in particular hemorrhagic and / or ischemic, stroke signs (SZ) by applying an algorithm for identifying stroke signs (53) to the artifact-reduced image data set (AD1), - Generating (61) an evaluation data set (BD1) by applying an algorithm to the artifact-reduced image data set (AD1) for evaluating an expression of the identified stroke signs (SZ), - Provision of the evaluation data set (BD1). The invention also relates to a medical X-ray device (37) and a computer program product. |
