Abstract
The invention relates to a method and a device for the separate three-dimensional representation of arteries and/or veins in a vascular system of the body by means of a C-arm biplanar system having two C-arms, which can each record a sequence of x-ray images from different projection angles during a mask or filler pass. With the filler pass, both C-arms record x-ray images, so that the x-ray images of the filler pass can be combined to form a first data record, which contains x-ray images from the arterial phase of the vascular contrasting and/or to form a second data record, which contains x-ray images from the venous phase of the vascular contrasting. This enables the arterial and venous phases to be reconstructed separately.
