Implementation of EvTool, a quantitative and radiobiological evaluation system, in a commercial RTPS

Abstract

The fast evolution of 3D Treatment Planning Systems of last few years, make necessary having available a system of evaluation of RT plans and comparison between them. At now the individuation of the best plan, i.e. the more similar to the optimal one, present more and more difficulties because of the continuos growing of the techniques’ complexity, made available by new hardware and software instrumentation. For this reason an exclusively qualitative evaluation of the plan and comparison between plans is not still adequate, or at least not sufficient, for the purpose of making real 3D treatments. In order to solve this problem, our group at the Biophysics Laboratory of the National Cancer Institute of Genoa developed EvTool, a system that allow the user to have quantitative and/or radiobiological helping to answer to the important question: which is the best plan? The author is now implementing EvTool inside the 3DLine RTPS ERGO, to use it as evaluation module for the RT plans of 3DLine Dynamic double-focused MultiLeaf Collimator System.
