Article
Full-text available
Ion beam therapy enables a highly accurate dose conformation delivery to the tumor due to the finite range of charged ions in matter (i.e., Bragg Peak (BP)). Consequently, the dose profile is very sensitive to patients anatomical changes as well as minor mispositioning, and so it requires improved dose control techniques. Proton Interaction Vertex...
Thesis
L'hadronthérapie est une modalité de radiothérapie innovante dans laquelle des ions légers -tels des protons ou des ions carbone- sont accélérés à une vitesse relativiste, puis focalisés afin d'irradier la zone tumorale du patient. Cette technique se démarque de la radiothérapie dite conventionnelle utilisant des photons- par l'existence d'un pic d...
Article
Trimethyl bismuth (TMBi) is a “heavy” transparent and dielectric organometallic liquid. This paper focuses on the measurement of TMBi’s optical properties relevant for particle detection. We measured the TMBi transmission curve and refraction index versus wavelength, as well as the light production yield and the timing performance on a small size c...
Article
Longitudinal prompt-gamma ray profiles have been measured with a multi-slit multi-detector configuration at a 75 MeV/u 13 C beam and with a PMMA target. Selections in time-of-flight and energy have been applied in order to discriminate prompt-gamma rays produced in the target from background events. The ion ranges which have been extracted from eac...

Proton imaging can be seen as a powerful technique for on-line monitoring of ion range during carbon ion therapy irradiation. The protons detection technique uses, as three-dimensional tracking system, a set of CMOS sensor planes. A simulation toolkit based on GEANT4 and ROOT is presented including detector response and reconstruction algorithm.
Article
A Compton camera is being developed for the purpose of ion range monitoring during hadrontherapy via the detection of prompt-gamma rays. The system consists of a scintillating fiber beam tagging hodoscope, a stack of double sided silicon strip detectors (90 x 90 x 2 mm(3), 2 x 64 strips) as scatter detectors, as well as bismuth germanate (BGO) scin...

2012 is the penultimate year of financial support by the CPER 2007-2013 for ETOILE's research program, sustained by the PRRH at the University Claude Bernard. As with each edition we make the annual review of the research in this group, so active for over 12 years now. Over the difficulties in the decision-making process for the implementation of t...
Conference Paper
Full-text available
Prompt secondary radiations such as gamma rays and protons can be used for ion-range monitoring during ion therapy either on an energy-slice basis or on a pencil-beam basis. We present a review of the ongoing activities in terms of detector developments, imaging, experimental and theoretical physics issues concerning the correlation between the phy...
Conference Paper
Trimethyl bismuth (TMBi) is a "heavy" organometallic liquid: 82% by weight of Bismuth. TMBi is a transparent and dielectric liquid that efficiently converts through the photo-electric effect photons of energies below 1 MeV. Charge and light produced in the liquid are both detected in a CaLIPSO detector. This paper focuses on the measurement of the...
