Abstract

The invention relates to a method of detecting the shape of a treatment device (3), in which the treatment device (3) is referenced in a computer-controlled, camera-assisted navigation system by means of a positional marker array (4) attached to the treatment device (3), wherein, by means of at least one radiographic image, projections of the treatment device (3) are detected and, via the position of the positional marker array (4) in the projections, the total outer shape of the treatment device (3) is assigned in the navigation system.
