    Exploiting symmetries for weight matrix design in CT imaging 
    Rodríguez-Álvarez, María-José; Sánchez Martínez, Filomeno; Soriano Asensi, Antonio; Iborra Carreres, Amadeo; Mora Mora, Cibeles (Elsevier, 2011-10)
    In this paper we propose several methods of constructing the system matrix (SM) of a Computed Tomography (CT) scanner with two objectives: (1) to construct SMs in the shortest possible time and store them in an ordinary ...

    New pixellation scheme for CT algebraic reconstruction to exploit matrix symmetries 
    Mora Mora, María Teresa Cibeles; Rodríguez Álvarez, María José; Romero Bauset, José Vicente (Elsevier, 2008-08)
    In this article we propose a new pixellation scheme which makes it possible to speed up the time of reconstruction. This proposal consists in splitting the field of view of the scanner into as many circular sectors as ...
