Abstract:
1. A method for extending a display range of a 2D image of an object region, comprising the steps of: providing multi-dimensional image data from a larger object area of a subject to a processor; acquiring at least one additional set of 2D image data from only a smaller object area, within said larger object area by exposing said subject to a data acquisition procedure in which 2D image data are acquired only from said smaller object area, and providing said at least one additional set of 2D image data to said processor; in said processor, bringing said multi-dimensional image data into registration with said additional set of 2D image data using a projection geometry; displaying an image of the larger object area represented by the multi-dimensional image data at an image display; and within the display of the larger object area at said image display, said processor causing at least temporary display of a 2D image represented by said additional set of 2D image data, by replacing image data in said multi-dimensional image data, which represent said smaller image area, with image data from said additional set of 2D image data.
