Abstract

Inhomogeneity correction factors for various field size and for various photon energies were demonstrated. Off center ratios in the inhomogeneous phantom for various photon energies were also shown. The influence of field size on dose distribution in an inhomogeneous material was considered to be important in planning irradiation of the thorax.
