Heterogeneity correction validation
o
Important to understand the implementation of the
heterogeneity corrections and also their limitations.
o
Important to know what dose is being reported:
o
Dose to water or dose to media
o
Any heterogeneous phantom available can be used. A reasonable
phantom is a slab phantom with water equivalent+low density
material+water equivalent.
o
Use small fields (5x5 cm2) because discrepancies are maximized.
