Prontontherapy

The nuclear physics group (GFN) collaborates with HC Hospitales Marbella (http://www.hcmarbella.com/) as an external advisor in preparation of the future Marbella PTC (Marbella Proton Therapy center), currently in its planning phase. The GFN collaborates in the preparation of all technical documents leading to a public tender for equipment selection and facility planning, including vendor selection and shielding calculations.

The group also collaborates with the physics department of Ruber International hospital, in two projects for dose monitorization of standard LINACs and Cyberknife devices using gammaacoustic equipment and fast scintillating crystals.

In December 2016, the group organized and hosted the 1st Spanish Workshop in Protontherapy (http://nuclear.fis.ucm.es/wep2016), with over 200 international attendees, participation of 8 industrial vendors (including Varian, RaySearch, Siemens, IBA, Hitachi or Phillips) and over 10,000 € in sponsorships.

Dr. Daniel Sánchez Parcerisa developed and maintain the proton treatment planning system FoCa (http://nuclear.fis.ucm.es/foca/), an in-house modular treatment planning system, developed entirely in MATLAB, which includes forward dose and LET calculation of proton radiotherapy plans in both active and passive modalities as well as a generic optimization suite for inverse treatment planning. The software has a dual education and research purpose. From the educational point of view, it can be an invaluable teaching tool for educating medical physicists, showing the insights of a treatment planning system from a well-known and widely accessible software platform. From the research point of view, its current and potential uses range from the fast calculation of any physical, radiobiological or clinical quantity in a patient CT geometry, to the development of new treatment modalities not yet available in commercial treatment planning systems. This software is a collaboration with the University of Pennsylvania (Philadelphia, PA), an Ivy League school and world-reference hospital in radiation oncology. The collaboration with the University of Pennsylvania extends to another project involving ionoacoustic verification of proton beams with wide-bandwidth hydrophones developed in collaboration with CSIC.

Dr. Sánchez-Parcerisa also collaborates with the UCLouvain (Belgium) and Washington University St. Louis (USA) in the development of new algorithms for proton therapy dose and linear energy transfer calculation in patient geometries.
