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.
