Forward Planning / Optimization
Catheter Geometry-based Adjustment of Dwell Times T
i
(Geometrical “
Optimisation
”, GO, G. Edmundson, 1990)
It is a “Catheter-Centric” Method
The Basic Principe is: Each SDP shall “feel” the
Existence of neighbouring SDPs (
SDPs socialisation
)
Developed by G. Edmundson at a period, where no 3D
anatomy model was available for planning (late 80’s)
If
dose distribution around catheters is adequate
and if
catheter geometry fits to anatomy-topology, then the dose
distribution is clinically acceptable with respect to anatomy
