What are the three components of the penumbra? - geometry, transmission, and lateral scattering Geometric Penumbra - is due to the finite source size. It is more of a concern in Co-60 machines where the source is between 1 and 2 cm in size. Transmission Penumbra - is due to the transmission of photons through the primary, secondary, or tertiary collimators Lateral Scattering - is the scatters from the irradiated volume at the field edges Physical Penumbra - is a combination of the geometri...
