Tomography system and method for visualizing a tomographic display

A tomography system and a method are disclosed for visualizing a tomographic display. The system, in at least one embodiment, includes a detector system for scanning an object, an arithmetic logic unit for conditioning the data determined by the scanning, and a device for visualizing tomographic image data of the scanned object with a first image resolution. According to at least one embodiment of the invention, the device for visualizing the tomographic image data has a selectable display function by which a subregion of the visualization is marked, and this marked subregion is simultaneously displayed in a second, relatively higher image resolution in addition to the visualization in the first image resolution, the calculation of the tomographic display being performed with the first, relatively low resolution, and a recalculation with the set, relatively higher resolution being carried out for the marked subregion.
