Stereotactic-radiation-therapy field monitoring using scintillating waveguides ribbon technology

We propose a novel field-monitoring system for Stereotactic Radiation Therapy (SRT) based on scintillating waveguides ribbons with output image acquisition. Waveguides ribbons are realized in two ways: micro-structuring a scintillating sheet and using the SciFi detector technology. Both technologies provide sub-millimeter waveguide pitches suitable for SRT-field monitoring. The proposed system implemented in three different prototypes has been tested in clinical conditions. The obtained results from both ribbon technologies confirm suitable sensitivity and spatial resolution for SRT QA procedures.
