1. An apparatus for displaying a reference image of a subject, and slices of said subject to be measured in the displayed reference image, for individually positioning two-dimensional slices in preparation for a subsequent slice-by-slice measurement of said subject, comprising:

  • a storage device for storing at least one reference image of current patient;

    a display screen for displaying the stored reference image as a two-dimensional structure;

    an input device for entering commands for displaying and positioning slices of said current patient to be measured, in the displayed reference image;

    a processing device connected to said storage device, said display screen and said input device, for processing the commands entered via said input device and for controlling display of said reference image and said slices on said display screen, said processing device, dependent on the commands entered via said input device, generating a perspectively rotated representation of said reference image and a spatial representation, indication corresponding to the perspective rotation of the reference image, of said layers, and causing said perspectively rotated representation to be displayed on said display screen together with said spatial representation indication, said processing device generating a perspectively rotatable frame around said reference image on said display screen as said spatial representation indication, and generating the perspectively rotated representation of said reference image together with said perspectively rotated frame as an at least two-dimensional structure on said screen that is rotated in a same direction as said perspectively rotated representation of said reference image.
