Small field dose calculation accuracy

General purpose TPS are not designed to be used in small fields

Design performance tests to check the capability of the calculation algorithms for small fields

❑ Define the conditions for the test:

simple/baseline conditions

treatment plans

❑ Select the data against which the TPS calculation will be compared (reference data) Measurements: detector/phantom Calculation: other TPS/algorithm; MC...

❑ Compare TPS calculation with the reference data;

Tolerance levels.
