Abstract
The invention relates to an X-ray imaging device (10) for an object, an X-ray imaging system (100) for an object, an X-ray imaging method for an object, and a computer program element for controlling such device or system and a computer readable medium having stored such computer program element. The X-ray imaging device (10) comprises a receiving unit (11) and a processing unit (12). The receiving unit (11) is configured to receive attenuation data representing attenuation properties of the object for at least two different X-ray spectra. The processing unit (12) is configured to decompose the attenuation data into decomposed data, to reduce noise in the decomposed data to obtain de-noised data, to back-convert the de-noised data into back-converted attenuation data, to combine back-converted attenuation data and the attenuation data into combined attenuation data, and to decompose the combined attenuation data into combined decomposed data.
