Abstract

In a method to extend the display range of 2D image recordings of an object region, particularly in medical applications, first 2D or 3D image data are acquired from a larger object region, and at least one additional set for 2D image data of a smaller object region is acquired that lies within the larger object region The first 2D or 3D image data are brought into registration with the additional 2D image data with a projection geometry. From the first 2D or 3D image data, an image data set is generated for an image display of the first object region, which is suitable for combination with the additional 2D image data. In the image display of the larger object region, at least temporarily, at least one display of the additional 2D image data is integrated, by image data in the first image data set, for the image display of the larger object region, being replaced with image data from the additional 2D image data representing the smaller image region. An overview of the larger object region is thus enabled, with the smaller object region of interest being displayed within the image in a more up-to-date fashion, as well as with higher resolution and/or higher contrast.
