A data processing unit receives a reference image (IMG13D) of a deformable physical entity, a target image (IMG23D) of said physical entity, and a first region of interest (ROI13D) defining a first volume in the reference image (IMG13D) representing a reference image element. The reference image (IMG13D), the target image (IMG23D) and the first region of interest (ROI13D) all contain 3D datasets. In response to user commands (c1; c2), the data processing unit defines a first contour (C12D) in a first plane through the target image (IMG23D), which is presented to a user via a display unit together with graphic data reflecting the reference image (IMG13D), the target image (IMG23D) and the first region of interest (ROI13D). The first contour (C12D) is aligned with at least a portion of a first border (IEB1) of a target image element (IE3D) in the target image (IMG23D). The target image element (IE3D) corresponds to the reference image element in the reference image (IMG13D). Based on the first contour (C12D), the target image (IMG23D) and the first region of interest (ROI13D); the data processing unit determines a second region of interest (ROI23D) defining a second volume in the target image (IMG23D). |
