Fully-organic flexible detectors for real-time dose monitoring during radio/proton therapy — •Beatrice Fraboni — Department of Physics and Astronomy , University of Bologna, Italy

The development of detectors for high energy ionizing radiation is a long-lasting research topic not only for fundamental applications but also for medical applications in radio and hadron therapy. Innovative sensors are needed, able to provide, in-situ and in real-time, an accurate recording and mapping of the dose delivered during a treatment plan. Organic small molecules and polymers are promising active layers for advanced dosimetry purposes, as their mechanical features allow the development of devices able to adapt to complex contoured surfaces with outstanding portability (low power operation) and lightweight. They also provide the unique possibility to develop human-tissue-equivalent dosimeters, thanks to their density and composition. The physical process of radiation detection for organic thin- film based detectors will be discussed in two different configurations: 1) the direct one, based on a simple planar device with an organic thin film as active conversion layer, and 2) the indirect one, based on a polysiloxane-based scintillating layer effectively coupled to an organic phototransistor (OPT). A new kinetic model has been developed to describe the organic dosimeter response mechanism under photon/proton irradiation and to provide further insight into the physical processes controlling its response.
