A method of correcting X-ray image data comprising information regarding a decay process of a radioactive material

摘要

The invention relates to a method for correcting X-ray image data of an examination object, which are acquired for an acquisition period with an X-ray detector of an X-ray system simultaneously with a decay process of a radioactive material taking place in or on the examination subject, the X-ray image data containing information regarding an X-ray attenuation distribution of the examination subject and information regarding the decay process include. The method comprises the following steps: determining correction image data representing the information relating to the decomposition process in the X-ray image data for the acquisition period, and generating corrected X-ray image data for the acquisition period using the X-ray image data and the correction image data. The invention also relates to a corresponding computer program, a corresponding data carrier, a corresponding data processing device and a corresponding X-ray system.
