DETERMINATION APPARATUS FOR DETERMINING THE POSE AND SHAPE OF AN INTRODUCTION ELEMENT

摘要

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 (12) is adapted to be used by a brachytherapy apparatus for introducing a radiation source (10) close to a target object (11) to be treated. A position determination element (27) like guidewire (20) with an electromagnetic tracking element (16) is introduced into the introduction element (12) such that it is arranged at different locations within the introduction element (12), wherein the positions of the position determination element (27) within the introduction element (12) 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.

主权项

1. A determination apparatus for determining the pose and shape of an introduction element 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 within the living being, the determination apparatus comprising:
a position determination unit comprising a position determination element for being introduced into the introduction element such that the position determination element is arranged at different locations within the introduction element, wherein the position determination unit is adapted to determine positions of the position determination element at the different locations within the introduction element, an acquisition unit for acquiring the determined positions of the position determination element for determining the pose and shape of the introduction element within the living being, and a control unit for controlling the acquisition depending on the determined positions.
