Patent ID: 8229198

Claim:
A method for creating an image recording of a blood vessel system of a patient using a detector of a medical device, comprising: administering a contrast agent; recording a first image recording of the blood vessel system in a first image recording region of a first position of the detector; observing a diffusion of the contrast agent in a predetermined direction of the first image recording region for determining a current diffusion position; moving the detector to a second position in the predetermined direction as a function of the current diffusion position; recording a second image recording of the blood vessel system in a second image recording region of the second position of the detector; defining a part of the first image recording without the contrast agent recorded in a region between the current diffusion position and an end of the first image recording region as a mask; evaluating a locationally correlated part of the second image recording with the contrast agent using the mask for a digital subtraction angiography; and creating the image recording by the digital subtraction angiography wherein the detector, the first image recording region or the second image recording region are divided into three equally sized parts, wherein a first part acquires a fill image, a second part observes the contrast agent for determining the diffusion position and a third part acquires the mask.
