Performance testing – drawnbacks of this approach
Advantages:
•
The results only depend on beam modeling and the calculation
algorithms as implemented in the TPS.
•
Ideal for TPS comparison as avoids uncertainties due to different
set of measurements performed at different sites at different
times.
Disadvantages:
•
Different planning systems need different data
•
Some of them require tunning of parameters
•
Need of modeling a “new beam” with no clinical application
•
Difficult to have a good data set for beam configuration that can
be used in all planning systems.
