TRS-483: formalism for
reference
dosimetry in FFF beams
in FFF beams
Main issues to consider that lead to differences in beam
quality correction factors between WFF and FFF :
b)
Differences in (Sw,air)
Q
as a function of BQI
c)
Differences in perturbations factors, other than p
vol
d)
Volume averaging due to the non-uniform lateral beam
profile
In TRS-483:
Corrections tabulated vs BQI
