Fluorescence spectroscopy has long been one of the most useful
bio-physical techniques available to scientists studying the
structure and function of biological tissues due to high sensitivity
of fluorescence signal to variations of optical properties of tissues
as a result of structural variations.
To calculate the dose distributions of 6 MeV photon beam at variable depth
in 3D water phantom the MCNP4C2 code was used, and the simulated dose
profile was compared with that of the treatment planning computer system
(TPS), and a good agreement w
as found between them.
In conclusion, the MCNP4C2 code package presents a good tool adaptable
to get dose distributions for the 6MeV photon beam and it can be considered as
confirmed method for patient dose calculations.
