Method for illustrating anatomical patient structures of the section in question on an imaging device

The method involves determining a position of a patient structure in a patient coordinate system. A position of a region of interest is defined in an image detection apparatus coordinate system. A medical tracking system is used to track position changes between an image detection apparatus relative to the structure in the system. The defined position of the region of interest in the image coordinate system is changed in accordance with position changes between the apparatus relative to the structure. The structure and/or properties of the structure is displayed. Independent claims are also included for the following: (1) a computer program for displaying an anatomical patient structure in a region of interest of a movable image detection apparatus (2) a system for detecting an anatomical patient structure in a region of interest of a movable image detection apparatus.
