Correction for volume averaging

Small fields: relative dosimetry in practice

Derived from an integration of the 3D dose distribution in the water

phantom over the

volume

of the detector.

For example:

Morin et al MP, 40(1), 2013

Defined as the inverse of the detector signal integrated over its

area

and

weighted by the off-axis ratio from film measurements (film profiles)
