“…A number of authors have proposed that photon dose be calculated using convolution mathematics (Dean 1980, Mackie 1983, Mackie and Scrimger 1984, Boyer and Mok 1984, Ahnesjo 1984, Boyer 1984 , Mackie et a1 1985b, Mohan et a1 1986. The technique involves convolving the primary photon fluence with a kernel that describes the transport and deposition of energy by secondary particles.…”

The EGS Monte Carlo code was used to generate photon energy deposition kernels which describe the energy deposited by charged particles set in motion by primary, first scattered, second scattered, multiple scattered and bremsstrahlung plus annihilation photons. These were calculated for a water medium irradiated with monoenergetic photons with energies in the range 0.1-50 MeV. In addition to the primary energy deposition kernels, primary charged particle transport was further characterised by computing the effective centre of the voxels, and the effective penetration depth, effective radius and effective lateral distance travelled by these particles. The dose per unit collision kerma for parallel monoenergetic primary photons beta' was calculated. Additional applications of the energy deposition kernels are discussed.
