Understanding the purpose of modelling parameters... Pinnacle

Effective Source Size parameters -> penumbra Rounded leaf end radius –> raytraced attenuation -> penumbra Energy spectrum -> depth doses Electron contamination parameters -> buildup part of depth doses Infield parameters -> open beam fluence profile Spectral off-axis softening -> attenuation variation off-axis Interleaf leakage –> “wiggling” in out-of-field profiles Transmission factors -> “bottom” part of out-of-field profiles Flattening Filter Scatter Source -> output factor & out of field profile

Manual parameter tuning <-> Automodeling ?
