González Martínez, Antonio Javier; Gonzalez-Montoro, A.; Aguilar, A.; Cañizares, G.; Martí, R.; Iranzo, S.; Lamprou, E.; Sánchez, S.; Sánchez, F; Benlloch Baviera, Jose María (IOP Publishing, 2017-12-11)
AMIC: an expandable integrated analog front-end for light distribution moments analysis

Spaggiari, Michele; Herrero Bosch, Vicente; Lerche, Christoph Werner; Aliaga Varea, Ramón José; Monzó Ferrer, José María; Gadea Gironés, Rafael (IOP Publishing: Hybrid Open Access, 2011-01)

In this article we introduce AMIC (Analog Moments Integrated Circuit), a novel analog Application Specific Integrated Circuit (ASIC) front-end for Positron Emission Tomography (PET) applications. Its working principle is ...
Cálculo tridimensional de dosis en tratamientos de CT/SPECT con emisor interno Lu-177 mediante técnicas Monte Carlo

Codosero Navarro, Claudia (Universitat Politècnica de València, 2019-10-21)

[ES] La dosimetría personalizada y precisa del tratamiento con Lutecio-177 (177Lu) en tumores endocrinos es esencial, ya que la absorción y la eliminación varían entre los pacientes. Este trabajo presenta una metodología ...
Desarrollo de una herramienta de segmentación automática de los lóbulos pulmonares y del cálculo de la perfusión pulmonar en imágenes de TC y SPECT

Fuster Palop, Javier (Universitat Politècnica de València, 2020-07-28)

[ES] Las patologías pulmonares cada vez afectan a más población hasta el punto de que se estima que la Enfermedad Pulmonar Obstructiva Crónica (EPOC) se va a convertir en la tercera causa de muerte a nivel mundial en la ...
Evaluation of a timing integrated circuit architecture for continuous crystal and SiPM based PET systems

Monzó Ferrer, José María; Ros García, Ana; Herrero Bosch, Vicente; Perino Vicentini, Ivan Virgilio; Aliaga Varea, Ramón José; Gadea Gironés, Rafael; Colom Palero, Ricardo José (IOP Publishing: Hybrid Open Access, 2013-03)

[EN] Improving timing resolution in positron emission tomography (PET), thus having fine time information of the detected pulses, is important to increase the reconstructed images signal to noise ratio (SNR) [1]. In the ...
PETIROC2 based readout electronics optimization for Gamma Cameras and PET detectors

Monzó Ferrer, José María; Aguilar -Talens, Albert; González Montoro, Andrea; Lamprou,E.; González Martínez, Antonio Javier; Hernández Hernández, Liczandro; Mázur, Dmytro; Colom Palero, Ricardo José; Benlloch Baviera, Jose María (IOP Publishing, 2017)
