    2D study of a joint reconstruction algorithm for limited angle PET geometries 
    Vergara, Marina; Rezaei, Ahmadreza; Rodríguez-Álvarez, Maria Jose; Benlloch Baviera, Jose María; Nuyts, Johan (KU Leuven, 2021-07-23)
    [EN] Recently, a wide interest on organ-dedicated PET systems has been shown. Some of those systems present geometries that produce an incomplete sampling of the tomographic data due to limited angular coverage and/or ...
