This paper describes recent numerical simulation results of some experiments
carried out by Nooru-Mohamed to study mixed mode fracture of concrete. The numerical
simulation is based on a meso-mechanical model developed ...
PenMesh-Monte Carlo radiation transport simulation in a triangle mesh geometry
(2009-12)
Article.
Accés obert
Article.
Accés obert
We have developed a general-purpose Monte Carlo simulation code, called penMesh, that combines the accuracy of the radiation transport physics subroutines from PENELOPE and the flexibility of a geometry based on triangle ...
Effect of oblique X-ray incidence in flat-panel computed tomography of the Breast
(2009)
Article.
Accés obert
Article.
Accés obert
We quantify the variation in resolution due to
anisotropy caused by oblique X-ray incidence in indirect flat-panel
detectors for computed tomography breast imaging systems. We
consider a geometry and detector type ...

3I is a commonly used radioisotope employed in
neurotransmitter SPECT studies. In addition to an intense line
at 159 keV, the decay scheme of this radioisotope includes a low
yield (∼3%) of higher energy photons which ...
Quantification of dopaminergic neurotransmission SPECT studies with I-123-labelled radioligands. A comparison between different imaging systems and data acquisition protocols using Monte Carlo simulation

Accés restringit per política de l'editorial
Purpose 123I-labelled radioligands are commonly used for
single-photon emission computed tomography (SPECT)
imaging of the dopaminergic system to study the dopamine
transporter binding. The aim of this work was to ...

PENELOPE-2008: A Code System for Monte Carlo Simulation of Electron and Photon Transport
(2009)
Working paper.
Accés obert
Working paper.
Accés obert
The computer code system PENELOPE (version 2008) performs Monte Carlo simulation of coupled
electron-photon transport in arbitrary materials for a wide energy range, from a few hundred eV to
about 1 GeV. Photon transport ...

Results for naturally occurring 7Be, 210Pb, 40K, 214Bi, 214Pb, 212Pb, 228Ac and 208Tl and anthropogenic 137Cs
in airborne particulate matter in the Barcelona area during the period from January 2001 to December
2005 are ...
Absolute quantification in dopaminergic neurotransmission SPET imaging using a Monte Carlo-based scatter correction and fully 3D reconstruction

Article.
Accés restringit per política de l'editorial
Dopamine transporter (DAT) ligands have been developed for in vivo imaging of the dopaminergic system in SPECT. Although the visual analysis of SPECT images is, in general, suitable for
clinical assessment, the accurate ...
Comparison between PENELOPE and electron Monte Carlo simulations of electron fields used in the treatment of conjunctival lymphoma

Article.
Accés restringit per política de l'editorial
For the treatment of conjunctival lymphoma in the early stages, external beam radiotherapy offers a curative approach. Such treatment requires the use of highly conformed small radiation beams. The beam size is so small ...
