Abstract Nuclear physics processes are an important source of uncertainty in dose calculations in particle therapy and radioprotection in space. Accurate cross section measurements are a crucial ingredient in improving the understanding of these processes. The FOOT (FragmentatiOn Of Target) experiment aims at measuring the production cross sections of fragments for energies, beams and targets that are relevant in particle therapy and radioprotection in space. An experimental apparatus composed o...

Abstract FOOT (FragmentatiOn On Target) is an applied nuclear physics experiment aimed at measuring the production cross sections of fragments for energies, beams and targets relevant in particle therapy and radioprotection in space. The Δ E-TOF detector will measure the energy deposited by the fragments in a wall of plastic scintillators and the time of flight with respect to a start detector. These two quantities allow to determine the charge Z of the fragment. In this work, we summarize the c...

Abstract Particle therapy uses proton or 12 C beams to treat deep-seated solid tumors. Due to the advantageous characteristics of charged particles energy deposition in matter, the maximum of the dose is released to the tumor at the end of the beam range, in the Bragg peak region. However, the beam nuclear interactions with the patient tissues induces fragmentation both of projectile and target nuclei and needs to be carefully taken into account. In proton treatments, the target fragmentation pr...

Abstract Positron emission tomography (PET) is one of the most mature techniques for monitoring in ion beam therapy. PET allows to reconstruct the β + activity generated in the patient by the nuclear interaction of the ions. Taking advantage of the spatial correlation between positron emitters created along the ions path and the dose distribution, it is possible to perform a quality control of the treatment. Usually, to reconstruct the activity generated within the irradiated volume, standard 3D...

Abstract The FOOT experiment aims at identifying the fragments produced in the human body during hadrontherapy and at measuring their cross sections. The apparatus is composed of several detectors which allow a complete reconstruction of the tracks of the fragments. In particular, the Δ E-TOF detector measures the energy released in a thin plastic scintillator and the time of flight of the fragments. In this work, we report the energy and time resolution of a Δ E-TOF detector prototype with prot...

Power supply of positron emission tomography (PET) detectors is a serious issue for PET/magnetic resonance imaging (MRI) systems, due to mutual interaction between power supply electronics and MRI magnetic fields. We developed a prototype of a magnetic compatible power supply, that can be placed in an MRI system. The power supply is a compact ( 5.2\times 5.2cm2) iron-free switching dc–dc converter. The power supply works in the very high frequency (VHF) range, between 24.5 and 26.5 MHz, to al...

The TRIMAGE project aims at developing a brain-dedicated PET/MR/EEG system able to perform simultaneous PET, MR, and EEG acquisitions for application in schizophrenia. Both PET and MR components have been designed in this project. The PET component consists of a full ring with 18 sectors each comprising three square detector modules. The modules are based on dual-layer staggered matrices of LYSO crystals read out by silicon photomultipliers. This paper describes in full detail the final version ...

Abstract Silicon photomultipliers (SiPMs) are becoming the reference photodetectors in many fields. In medicine they are slowly replacing photomultiplier tubes and avalanche photodiodes in medical imaging and in PET in particular. In this paper a broad overview of the current applications of SiPM in medicine is presented. The major fields where the SiPMs are used, namely PET/MR and hadrontherapy are discussed at length.

Abstract This paper describes the development and characterization of a Δ E-TOF detector composed of a plastic scintillator bar coupled at both ends to silicon photomultipliers. This detector is a prototype of a larger version which will be used in the FOOT (FragmentatiOn Of Target) experiment to identify the fragments produced by ion beams accelerated onto a hydrogen-enriched target. The final Δ E-TOF detector will be composed of two layers of plastic scintillator bars with orthogonal orientati...
