Modern Brachytherapy Treatment Planning Catheters/Applicators (Sources) Localisation

The actual aim of the Localisation Process is:

to define the 3D-positions of the sources or of the possible source dwell positions and register these to the relevant anatomy (PTV, OARs).

This presumes:

• Localisation of the implanted Catheters/Needles/ Applicators and • Knowledge of Afterloader and Catheter/Applicator specific Information/Characteristics.
