title: Film-densitometric verification of the Hogstrom algorithm used in "PLATO" treatment planning system (TPS).
abstract: We consider dose distributions in suitable homogeneous and inhomogeneous phantoms irradiated with electron beams at a fixed energy (11MeV). Dose distributions were obtained by film densitometry on Kodak X-Omat V film, and compared to corresponding distributions computed by means of the Hogstrom algorithm, included in PLATO TPS by Nucletron. Principal critical points found when checking the algorithm, which could be significant in clinical practice, are briefly discussed.
