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.
