    ALBIRA: A small animal PET/SPECT/CT imaging system 
    Sánchez Martínez, Filomeno; Orero Palomares, Abel; Soriano Asensi, Antonio; Correcher Salvador, Carlos; Conde Castellanos, Pablo Eloy; González Martínez, Antonio Javier; Hernández Hernández, Liczandro; Moliner Martínez, Laura; Rodríguez Álvarez, María José; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María; Chapman, S.E.; Leevy, W.M. (American Association of Physicists in Medicine: Medical Physics, 2013-05)
    Purpose: The authors have developed a trimodal PET/SPECT/CT scanner for small animal imaging. The gamma ray subsystems are based on monolithic crystals coupled to multianode photomultiplier tubes (MA-PMTs), while computed ...

    Expectation maximization (EM) algorithms using polar symmetriesfor computed tomography(CT) image reconstruction 
    Rodríguez Álvarez, María José; Soriano Asensi, Antonio; Iborra Carreres, Amadeo; Sánchez Martínez, Filomeno; González Martínez, Antonio Javier; Conde, P.; Hernández Hernández, Liczandro; Moliner Martínez, Laura; Orero Palomares, Abel; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María (Elsevier, 2013-09-01)
    We suggest a symmetric-polar pixellation scheme which makes possible a reduction of the computational cost for expectation maximization (EM) iterative algorithms. The proposed symmetric-polar pixellation allows us to deal ...

    Minimization of parallax error in dedicated breast PET 
    Soriano Asensi, Antonio; González Martínez, Antonio Javier; Sánchez Martínez, Filomeno; Conde, Pablo; Moliner Martínez, Laura; Orero Palomares, Abel; Rodríguez Álvarez, María José; Vidal, Luis F.; Benlloch Baviera, Jose María (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)
    [EN] The increase of the detector thickness and the incidence angle of impinging photons permits an enhancement of sensitivity in positron emission tomography (PET) scanners. But also increases the parallax error and leads ...
