摘要

Method for digital subtraction angiography of a recording area of a patient, whereby- at least one mask image of the recording area is recorded without the use of a contrast agent, - several filling images are recorded after administration of a contrast agent, and- result images are determined by subtracting one of the at least one mask image from respective filling images, wherein Depending on an automatically determined or provided by the user, a suitability of the at least one mask image with regard to different movement states in the recording area when recording the at least one mask image and for at least some of the filling images describing image quality information if the at least one mask image is unsuitable for at least one filling image of an unsuitability group - At least one further mask image is recorded and the suitability of the further mask is automatically determined by means of a comparison algorithm image for which at least one filling image of the unsuitable group is checked with regard to the state of movement, and after suitable mask images are available for each filling image of the unsuitable group, the recording of further mask images is canceled.
