Auxiliary Apparatus for Assisting Brachytherapy, Brachytherapy System for Applying Brachytherapy to a Living Object, Auxiliary Method for Assisting in Brachytherapy, and Auxiliary Computer Program for Assisting in Brachytherapy in performing brachytherapy. The position of an introducer element (17), such as a catheter, is tracked particularly by the use of an electromagnetic trace, while a seed group is introduced into a living object (2). This provides a rough understanding of the position of the seeds within the object. An ultrasound image showing the group is generated, depending on the tracked position of the introducer element, and thus, depending on the approximate knowledge of the position of the seeds, to optimize the ultrasound visualization of the introduced seeds. Based on this ultrasound visualization, the position of a seed in the group is determined, thus allowing for improved determination of seed positions and, accordingly, enhanced brachytherapy is performed based on the determined positions. 1/1
