Assessment of induction of secondary tumours due to various radiotherapy modalities.

One of the objectives of the European Sixth Framework integrated project MAESTRO is to perform an assessment of risk due to various radiotherapy modalities, regarding secondary tumour induction. Initially, the study will focus on cancer of the prostate and the present work represents the first step towards that goal. One of the intended tools, to be used in the assessment, is the Monte Carlo radiation transport code ORANGE.

ORANGE, a new, fast dose engine for radiotherapy treatment planning.

A new Monte Carlo dose engine is introduced under the name of ORANGE. It is a general purpose and flexible program, because it is based on MCNP, and it is fast, because a fast dose algorithm has been added to it. In this paper it is shown that the dose results for photons and electrons are accurate within 2%, and that ORANGE can calculate accurate three-dimensional dose distributions in a 30 x 30 x 30 cm3 phantom with 60(3) voxels within a quarter of an hour on present day PCs, even before employing variance reduction techniques.

ORANGE: a Monte Carlo dose engine for radiotherapy.

This study presents data for the verification of ORANGE, a fast MCNP-based dose engine for radiotherapy treatment planning. In order to verify the new algorithm, it has been benchmarked against DOSXYZ and against measurements. For the benchmarking, first calculations have been done using the ICCR-XIII benchmark.
