Smart particle detector for hadron therapy

HadrontherapyParticle trackingResidual rang measurementScintillating optical fibersSmart read-out compression


The invention relates to particle detectors based on scintillating fibers. The combination of an innovative routing scheme of the fibers and a read-out channel compression system allows  the design of innovative, low cost and high performance trackers and residual energy detectors which constitute the building block of particle radiography, tomography or beam qualification in hadron-therapy.

Technical features

The maximum advantage from using charged particle beams in hadron-therapy, or in different fields of application, is reached when the stopping power of the particles is known with high precision. The direct use of this information leads to a more accurate evaluation of the distribution of the dose. The present invention relates to a method and two devices, explicitly designed for particle imaging applications in beam diagnostics and monitoring.  The use of scintillating fibers for the design of beam monitor and residual range detectors is advantageous because of the fast response and water equivalence. The developed technology exploit all these performances and add a smart read-out strategy. The architecture of these innovative detectors is thought as modular and the devices can work in combined modalities between them and other detectors. The real time performances allow the interface to beam control systems.
