Kernel-Based Methods
Combine an analytical calculation of the primary photon interactions with the subsequent transport and energy deposition by secondary particles described by pre- calculated kernels Point-spread kernel : Absorbed dose from both secondary electrons and photons around the interaction point Calculated by Monte Carlo in infinite medium of water since too chaotic (sometimes photoelectric, Compton, …) Energy spectrum derived from measurements (pdd)
