Embodiment Construction

[0055] figure 1 Schematically and exemplarily shown is a system for introducing an influencing element into a target, wherein the influencing element is adapted to influence a target region within the target. In this embodiment, the system is a brachytherapy system 1 for applying brachytherapy to a target area within a human body 2 lying on a table 3 . The brachytherapy system 1 comprises a placement unit 5 for being partly inserted into the human body 2 and for placing an influencing element, in this embodiment a radiation source, close to or in the target area , to direct the radiation emitted by the radiation source to the target area. figure 2 The placement unit 5 is exemplarily and schematically shown in more detail in .

[0056]The placement unit 5 comprises several introduction devices, in this embodiment catheters 12 , for being inserted into the human body 2 . The placement unit 5 also comprises several navigation elements 13, which are wires to which the radiatio...

Abstract

The invention relates to a calibration apparatus for calibrating a system for introducing an influencing element like a radiation source into an object, particularly for calibrating a brachytherapy system. First and second images show a longish introduction device (12) like a catheter and a tracking device (16) like an electromagnetically trackable guidewire inserted into the introduction device as far as possible,and the introduction device and a calibration element(46)having the same dimensions as the influencing element and being inserted into the introduction device as far as possible. A spatial relation between the tracking device and the calibration element is determined based on the images for calibrating the system. Knowing this spatial relation allows accurately determining an influencing plan like a brachytherapy treatment plan and accurately positioning the influencing element in accordance with the influencing plan, which in turn allows for a more accurate influencing of the object.

Description

technical field [0001] The invention relates to a calibration device, a calibration method and a calibration computer program for calibrating a system for introducing an influencing element into a target, wherein the influencing element is adapted to influence a target area within the target. In particular the invention relates to a calibration device, a calibration method and a calibration computer program for calibrating a brachytherapy system. The invention also relates to an influence plan determination device, an influence plan determination method and an influence plan determination computer program for determining an influence plan for influencing a target area within an object. The impact plan is preferably a treatment plan for a brachytherapy procedure. Background technique [0002] During a clinical high dose rate (HDR) brachytherapy procedure, a catheter is inserted into a target area in the human body, wherein, through the inserted catheter, a radiation source i...
