Abstract
The invention relates to a determination apparatus for determining the pose and shape of an introduction element like a catheter within a living being, wherein the introduction element is adapted to be used by a brachytherapy apparatus for introducing a radiation source close to a target object to be treated. A position determination element like guidewire with an electromagnetic tracking element is introduced into the introduction element such that it is arranged at different locations within the introduction element, wherein the positions of the position determination element within the introduction element are determined. The determined positions are then acquired depending on the determined positions for determining the pose and shape of the introduction element within the living being. This can lead to a determination procedure with reduced user interaction, thereby simplifying the determination procedure for the user.
