Method for the production of which is related to the vascular system of a patient by means of an image recording is in its position variable detector of a device for digital subtraction angiography with the following steps:- After administration of contrast medium production of at least one on the vascular system of the patient relative to the image recording (44) of a a first position of the detector associated first image acquisition range and observation and / or determination of the propagation of the contrast medium in a predetermined direction of the first image acquisition range for the determination of a current spreading position,- as a function of the determination of a certain current propagation position change of the position of the detector in the predetermined direction in a second position,- Production of at least one image recording (45) of one of the second position of the detector associated second image acquisition range and- Use of at least one of which is in the range between the determined current propagation position and the end of the first image acquisition range in the predetermined direction without contrast agent and thus is a part received in the first position of the detector created image recording (44) as a mask for the evaluation of a locally correlated with the contrast medium at least one part received in the second position of the detector created image recording (45) for the digital subtraction angiography.
