1. A method for retrieval and graphical visualization of multi-dimensional compressed image data on a screen client of an image archiving/retrieval and rendering system operating on a client/server basis, said method comprising the steps of:

  • requesting compressed volume data of a subject from a server by a screen client of the server for image rendering at the screen client, and transferring the requested compressed volume data from the server to the screen client and presenting the subject at the screen client in graphical form in a virtual subject space; and

    said screen client having a screen plane, and at said screen client, automatically partitioning said virtual subject space into a plurality of volume units of respectively different sizes, dependent on a depth distance of volume regions, to be presented by said volume units, from an observation point situated in front of said screen plane, said screen client decreasing the respective sizes of said volume units in a predetermined manner toward a direction of said observation point and loading compressed image data of lower resolution of a volume data set of the volume regions partitioned most coarsely and farthest from said observation point and successively downloading compressed image data of higher resolution, being less compressed in said direction of decreasing depth distance, for volume units of volume regions partitioned more finely in the direction of said observation point, and presenting volume regions with increasing proximity to said observation point at a higher, spatially variable depth detail level than volume units of said more coarsely partitioned volume regions farther from said observer.
