“…A strong case has been made for the adoption of SPECT/MRI for preclinical use. 14 In most of the experimental synchronous preclinical SPECT/MRI systems under study, arrays of CdTe or CdZnTe (CZT) gamma detectors are employed, 21,22 Similar solid-state technology is finding increasing use in clinical SPECT systems being used for cardiac imaging, 23,24 scintimammography 25 and, more recently, whole-body SPECT imaging. 26 As regards compatibility with MRI, preliminary investigations on CdTe and CZT have shown that a shift of the signal charge inside the detector caused by Lorentz forces takes place and this phenomenon requires correction to improve the detector response so as to achieve a high resolution.…”

There is increasing clinical use of combined positron emission tomography and MRI, but to date there has been no clinical system developed capable of simultaneous single-photon emission computed tomography (SPECT) and MRI. There has been development of preclinical systems, but there are several challenges faced by researchers who are developing a clinical prototype including the need for the system to be compact and stationary with MRI-compatible components. The limited work in this area is described with specific reference to the Integrated SPECT/MRI for Enhanced stratification in Radio-chemo Therapy (INSERT) project, which is at an advanced stage of developing a clinical prototype. Issues of SPECT/MRI compatibility are outlined and the clinical appeal of such a system is discussed, especially in the management of brain tumour treatment.

“…The gain was determined from the distance between pedestal and the first photopeak and between adjacent photopeaks. We took advantage of our previous experience with similar measurements using front-end and readout electronics based on an Application Specific Integrated Circuit (ASIC) tailored to SiPM readout and developed by our research group in collaboration with GM-IDEAS, as described in our earlier publications [8], [9], [10].…”

Particle detector prototypes equipped with Silicon Photomultipliers designed to be sensitive in the near-ultraviolet wavelength region (NUV-SiPM) were tested in a beam of relativistic ions with electric charge Z in the range, at energies 13 and 30 GeV/amu at CERN SPS. Two different prototypes of charged particle detectors were tested. The first one was a scintillating fiber hodoscope with individual fibers optically coupled to single SiPM devices. The second one consisted of an array of discrete SiPM sensors that were directly exposed to the ion beam to study their capability to trigger an avalanche in response to the ionization generated inside the silicon device. In this paper, we first report the results of the characterization and dedicated tests of the NUV-SiPM sensors that were carried out in our laboratory under controlled conditions; then, we discuss the analysis of the beam test data and the performance of both prototypes

“…This was made possible by the development of a custom ASIC (Application Specific Integrated Circuit), with 64 channels, carried out in collaboration with GM-Ideas, Norway [20]. A readout board -developed by our group [21] -with a 16 bit ADC and interfaced via the USB2 protocol to a PC, records both the pulse height of each fired channel and a time stamp generated when the signal crosses an individually adjustable threshold.…”

An high resolution FDIRC for the measurement of cosmic-ray isotopic abundances, Astroparticle Physics (2011Physics ( ), doi: 10.1016Physics ( /j.astropartphys.2011 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.An high resolution FDIRC for the measurement of cosmic-ray isotopic abundances AbstractMeasurements of the relative abundance of cosmic isotopes and of the energy dependence of their fluxes may clarify our present understanding on the confinement time of charged cosmic rays in the Galaxy. Experimental studies of these propagation clocks have been carried out by balloon and space missions at energies of a few 100 MeV/amu by means of detection techniques based on multiple dE/dx sampling, coupled with a measurement of the energy released in a thick absorber. At larger energies, the isotopic separation of light nuclei (as, for instance, 9 Be/ 10 Be) can be achieved by combining a precise measurement of the particle's rigidity with an high resolution determination of its velocity, via the observation of the Cherenkov effect in a radiator.In this paper, we propose the introduction -for the first time in a space experiment -of the DIRC technique (Detection of Internal Reflected Cherenkov light) for the identification of cosmic-ray isotopes. This type of detector has been successfully used in electron-positron colliders for particle identification and in particular for π-K separation. While for particles with unit charge the light yield is a limiting factor, in the case of a nucleus of charge Z the larger photostatistics (due to the Z 2 dependence of Cherenkov light emission) is the key to reach an adequate angular resolution to provide a mass discrimination for isotopes of astrophysical interest. We report on the early development phase of a DIRC prototype with a focussing scheme (FDIRC) to collect the Cherenkov light onto a detector plane instrumented with a Silicon PhotoMultiplier (SiPM) array.
