European NoVel Imaging Systems for ION therapy

European NoVel Imaging Systems for ION therapy.

Hadrontherapy is a highly advanced technique of cancer radiotherapy that uses beams of charged particles (ions) to destroy tumor cells. The different physical principles compared to photon beam therapy result in the fact that the highest dose is deposited at the very end of the particles range. Thus, it is possible to deliver a very high dose to the tumor while sparing the surrounding healthy tissue. However, the downside of the higher physical selectivity of ion beams is the larger impact of anatomic variations during therapy and the resulting treatment related errors. Consequently high-precision quality assurance (QA) is strongly required. Furthermore accurate positioning is a more demanding challenge for targeting moving organs and for adapting the treatment plan as the tumor shrinks or other anatomical changes occur.

In order to improve the QA tools for hadrontherapy the ENVISION project aims at developing solutions for real-time non invasive ion beam monitoring via PET and single particle detection principles, the precise determination of delivered dose, a fast feedback for adaptive treatment planning and real-time response to moving organs. The MedUni group works on a software tool to automate parts of the evaluation process, which is essential to bring the novel assessment tools into clinical operation for hadrontherapy centers all over Europe. All these centers, including the Austrian facility MedAustron in Wiener Neustadt, will benefit from the findings and research activities of the ENVISON project.
