Abstract

A system and apparatus for registering image data of a body, wherein the image data are captured in a detection range and the body is subsequently shifted relative to the detection range or vice versa. The image data are registered from the detected position of a first marker array, arranged in a defined positional relationship relative to the body, and from the detected position of a second marker array, arranged in a defined positional relationship relative to the detection range. The apparatus includes a camera and a first marker array that is arranged in a known positional relationship relative to the body, wherein a second marker array is arranged at a fixed position relative to a detection range.
