Abstract

The invention relates to a method for the production of angiography recordings. First, a mask image is recorded with a first modality. A contrast medium is injected after the first recording. A control image is recorded with a second modality after the injection of the contrast medium. A spreading of the contrast medium is determined based on the images and the control of subsequent recordings is analyzed. A recording criterion is checked to determine whether the recording criterion has been achieved. If it has not been achieved, the control image is repeatedly recorded for repeatedly determining the spreading of the contrast medium. If it has been achieved, a contrast image is recorded with the first modality and the mask image and the contrast image are processed and analyzed.
