Description
Computational tools originating from high energy physics developments provide
solutions to common problems in other disciplines: this study presents quantitative
results concerning the application of HEP simulation and analysis tools, and of the
grid technology, to dosimetry for oncological radiotherapy.
The study concerned all the three major radiotherapy techniques: therapy with
external beams from a medical linear accelerator (in particular, the modern technique
or intensity modulated radiotherapy), brachytherapy with internal or superficial
radioactive sources, and hadrontherapy with a proton beam. Geant4-based simulation
applications developed for three realistic use case highlight the high precision dose
calculation achievable; the simulation is complemented by AIDA-compliant analysis
tools for the manipulation of dose distributions relevant to clinical usage. The
application design exploits DIANE for transparent execution in sequential and
parallel mode, either on a local farm or on the grid and GANGA as a grid user interface.
Benchmarks for execution on the grid are presented; they highlight the capabilities
and current limitations for exploiting the grid in real-life applications in all
major branches of
oncological radiotherapy.
Computational tools for dosimetry based on HEP software systems couple high
precision, speed suitable to clinical environments and low cost: therefore, they
represent an alternative to commercial products of particular interest to developing
countries for oncologial radiotherapy or radiation protection applications.
