摘要

A method for preparing for brachytherapy, a brachytherapy method, and a brachytherapy system are provided and involve using an applicator to be placed onto a radiation source, and an applicator guide to be inserted into an object to be irradiated. The applicator guide being formed such that the applicator can be inserted into the applicator guide. A position and orientation of the applicator guide are sensed by a navigation system, a position and orientation of an insertion assistance graphic object in a graphical representation are determined based on the sensed position and orientation of the applicator guide by a data processing device and the insertion assistance graphic object is displayed in the graphical representation by a display device. By its shape and being presented in the graphical representation, the insertion assistance graphic object is suitable for making it easier for a viewer to insert the applicator into the applicator guide.
