    Calibration of Gamma Ray Impacts in Monolithic-Based Detectors Using Voronoi Diagrams 
    Freire, Marta; Gonzalez-Montoro, Andrea; Sánchez Martínez, Filomeno; Benlloch Baviera, Jose María; González Martínez, Antonio Javier (Institute of Electrical and Electronics Engineers, 2020-05)
    [EN] Molecular imaging systems, such as positron emission tomography (PET), use detectors providing energy and a 3-D interaction position of a gamma ray within a scintillation block. Monolithic crystals are becoming an ...

    Novel method to measure the intrinsic spatial resolution in PET detectors based on monolithic crystals 
    González, A.; Sanchez, Filomeno; Bruyndonckx, Peter; Cañizares-Ledo, Gabriel; Benlloch Baviera, Jose María; González Martínez, Antonio Javier (Elsevier, 2019-03-11)
    [EN] The main aim of this work is to provide a method to retrieve the intrinsic spatial resolution of a gamma-ray detector block based on monolithic crystals within an assembled scanner. This method consists on a discrimination ...

    Performance comparison of large-area SiPM arrays suitable for gamma ray detectors 
    Gonzalez-Montoro, Andrea; González Martínez, Antonio Javier (IOP Publishing, 2019-07)
    [EN] The use of photosensors of the type Silicon Photomultpliers (SiPM) has widely been extended in recent years for multiple applications in both research and industry. However, there is a lack of comparative studies of ...

    Simulation study of resistor networks applied to an array of 256 SiPMs 
    González Martínez, Antonio Javier; Moreno, Manuel; Barberá, Julio; Conde Castellanos, Pablo Eloy; Hernández Hernández, Liczandro; Moliner Martínez, Laura; Monzó Ferrer, José María; Orero Palomares, Abel; Peiró Cloquell, Antonio; Polo Collado, Ramiro; Rodríguez Álvarez, María José; Ros García, Ana; Sánchez Martínez, Filomeno; Soriano Asensi, Antonio; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)
    [EN] In this work we describe a procedure to reduce the number of signals detected by an array of 256 Silicon Photo-multipliers (SiPMs) using a resistor network to divide the signal charge into few readout channels. Several ...
