Abstract

Methods for performing digital subtraction angiography of a region of interest of a patient are described herein. The methods include acquiring a filled image data set of the region of interest by x-ray imaging and creating an angiography image data set by subtracting a mask image data set from the filled image data set, wherein an x-ray imaging device for x-ray imaging and a further imaging device for at least one additional imaging modality are co-registered and operable to acquire image data in the same field of view, wherein the imaging devices are used to simultaneously acquire the filled image data set using the x-ray imaging device and an anatomy data set using the further imaging device and the mask image data set in derived from the anatomy data set in a conversion process, which converts additional imaging modality image data into virtual x-ray image data.
