Advanced Brachytherapy Physics - Vienna 2016

Modern Brachytherapy Treatment Planning Catheters/Applicators (Sources) Localisation In contrast to ERT, where the set-up of the real Beams (irradiation) is based on:

• Immobilization of the patient as in planning process (CT) • (re)Positioning of the patient using the RP and the Machine Coordinate System (Laser Projection of Isocentre)  RP = Laser-Iso • Imaging-based (2D/3D) verification of Target/Anatomy position • Fully automatic set-up of the beams and MLC-configurations 1 2
