A process for the expansion of the spot display area being a volume increase of an object area

摘要

The present invention relates to a process for the expansion of the spot display area being a volume increase of an object area, in particular in medical applications, in which at least a first 3 - d - image data set of a larger object area is provided, at least one second 3 - d - image data set of a smaller object area is recorded, the inside of the larger object area, and the first 3 - d - image data set with the second 3 - d - image data set is registered. From the first 3 - d - image data set and the second 3 - d - image data set, a synthesized 3 - d - image data set in an image generated and visualized, wherein the smaller object area, representing the first 3 - d - image data in the first 3 - d - image data set by second 3 - d - image data of the second 3 - d - image data set, if appropriate after a corresponding adaptation of the first and / or of the second 3 - d - image data set, in an identical scaling be replaced and alignment. The present process makes it possible, thus, an overview of the larger object region, wherein the smaller object area of interest within the image with a higher accuracy as well as a higher resolution and / or a higher contrast can be displayed.
