Abstract
The present invention relates to subtraction imaging. In order provide further improved accuracy of masking images, a device () for digital subtraction imaging is provided comprising an image data input (), a data processor () and an output interface (). 3D image data () of a region of interest of an object is received that comprises a 3D representation of the object based on a reconstruction from a plurality of 2D projection images. Further, a 2D live X-ray image () of the region of interest is received. The 3D image data and the 2D live X-ray image are registered, wherein a matching pose of the 3D image data corresponding to the 2D live X-ray image is determined. A digitally reconstructed radiography is computed from the 3D image data based on the determined matching pose to generate a 2D mask image. For the 2D mask image, current data related to the 2D live X-ray image is used to achieve an adapted 2D mask image, wherein the data related tothe 2D live X-ray image comprises 2D live acquisition parameters and/or data of the 2D live X-ray image. The generated adapted 2D mask is subtracted image from the 2D live X-ray image a digital image highlighting changes in the region of interest is provided.
