Providing a result data set

A provision unit comprising:

• a computing unit having a processor and memory, wherein the processor and memory are configured to:
• acquire a medical image data set of an object under examination, wherein the medical image data set maps a change in the object under examination on a time-resolved basis, and wherein the change starts and/or ends at different locations and different points in time within the object under examination;
• and
• identify a spatiotemporal subregion in the medical image data set, wherein the spatiotemporal subregion maps the change in a region of interest of the object under examination, wherein the spatiotemporal subregion is delimited spatially by the mapping of the region of interest and temporally by an earliest start and a latest end of the change mapped at the locations within the region of interest, and wherein the earliest start and the latest end of the change are determined by comparing points in time of the start and/or the end of the change at the different locations within the region of interest;
• and
• an interface configured to provide a result data set based on the subregion of the medical image data set, wherein the result data set maps the region of interest on a time-resolved basis.
