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 ...
Asesoramiento y diseño ergonómico de la camilla para el mamógrafo MAMMI

Morales Martín, Iñigo; Navarro Garcia, Francisco Jose; López López, Joaquín; Atienza Vicente, Carlos Manuel; Solera Navarro, Mª Jesús; González Martínez, Antonio Javier; Caballero Ontanaya, Luis; Vidal San Sebastián, Luis Fernando; Moine, Séverine (Universitat Politècnica de València. Instituto de Biomecánica de Valencia, 2011-01)

[EN] The Instituto de Biomecánica (IBV) takes part in the development of a dedicated stretcher to be used with the new breast PET of the company ONCOVISION. This device called MAMMI is the clinical PET system with ...
Design of the PET–MR system for head imaging of the DREAM Project

González Martínez, Antonio Javier; Conde, P.; Hernández Hernández, Liczandro; Herrero Bosch, Vicente; Moliner Martínez, Laura; Monzó Ferrer, José María; Orero Palomares, Abel; Peiró Cloquell, Antonio; Rodríguez-Alvarez, M.J.; Ros García, Ana; Sánchez Martínez, Filomeno; Soriano Asensi, Antonio; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María (Elsevier, 2013-02-21)

In this paper we describe the overall design of a PET–MR system for head imaging within the framework of the DREAM Project as well as the first detector module tests. The PET system design consists of 4 rings of 16 ...
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 ...
Monolithic crystals for PET devices: optical coupling optimization

González Martínez, Antonio Javier; Peiró, A.; Conde, P.; Hernández Hernández, Liczandro; Moliner Martínez, Laura; Orero Palomares, Abel; Rodríguez-Álvarez, M.J.; Sánchez Martínez, Filomeno; Soriano Asensi, Antonio; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María (Elsevier, 2013-12-11)

[EN] In this work we present a method to efficiently collect scintillation light when using monolithic scintillator crystals. The acceptance angle of the scintillation light has been reduced by means of optical devices ...
Results of a combined monolithic crystal and an array of ASICs controlled SiPMs

Conde Castellanos, Pablo Eloy; González Martínez, Antonio Javier; Hernández Hernández, Liczandro; Bellido, P.; Iborra Carreres, Amadeo; Crespo Navarro, Efren; Moliner Martínez, Laura; Rigla, JP.; Rodríguez Álvarez, María José; Sánchez, F.; Seimetz, Michael; Soriano Asensi, Antonio; Vidal San Sebastián, Luis Fernando; Benlloch Baviera, Jose María (Elsevier, 2014-01)

[EN] In this work we present the energy and spatial resolutions we have obtained for a γ ray detector based on a monolithic LYSO crystal coupled to an array of 256 SiPMs. Two crystal configurations of the same trapezoidal ...
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 ...
