Feasibility Study of a Small Animal PET Insert Based on a Single LYSO Monolithic Tube

González Martínez, Antonio Javier; Berr, Stuart S.; Cañizares-Ledo, Gabriel; Gonzalez-Montoro, Andrea; Orero Palomares, Abel; Correcher Salvador, Carlos; Rezaei, Ahmadreza; Nuyts, Johan; Sanchez, Filomeno; Majewski, Stan; Benlloch Baviera, Jose María (Frontiers Media, 2018-11-28)

[EN] There are drawbacks with using a Positron Emission Tomography (PET) scanner design employing the traditional arrangement of multiple detectors in an array format. Typically PET systems are constructed with many regular ...
Motion Correction of Multi-Frame PET Data

Cañizares, Gabriel; Espinós-Morató, Héctor; Santos, Joaquín; Hernández, Ángel; Moliner, Laura; Álvarez-Gómez, Juan Manuel; González Martínez, Antonio Javier; Sánchez, F; Rodríguez-Álvarez, MJ.; Benlloch Baviera, Jose María (IEEE, 2019-11-02)

[EN] Motion correction algorithms are necessary in PET studies where the patient cannot remain totally static. Otherwise, artifacts appear in the final reconstructed image, degrading the spatial resolution or even misplacing ...
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 ...
