Comparison of the main magnetic resonance imaging acceleration strategies based on parallel imaging techniques

Acebrón Fabregat, Javier; Moratal Pérez, David; Marti Bonmati, Luis; Brummer, Marijn Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)

[EN] The main parallel imaging techniques have been implemented under MATLAB (SENSE, PILS and SPACE-RIP for image domain, and SMASH and GRAPPA for k-space domain), evaluating its characteristics about image quality and ...
Few-View CT Image Reconstruction via Least-Squares Methods: Assessment and Optimization

CHILLARÓN-PÉREZ, MÓNICA; Vidal-Gimeno, Vicente-Emilio; Verdú Martín, Gumersindo Jesús; Quintana-Ortí, Gregorio (Taylor & Francis, 2024-02-01)

[EN] The use of iterative algebraic methods applied to the reconstruction of computed tomography (CT) medical images is proliferating to reconstruct high-quality CT images using far fewer views than through analytical ...
Online QoS management for multimedia real-time transmission in industrial networks

Silvestre-Blanes, Javier; Almeida, L.; Marau, R.; Pedreiras, P. (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)

A growing number of industrial applications incorporate multimedia information processing. These multimedia applications are commonly distributed and subject to time constraints that must be met across networks without ...
Quality assurance applied to digital radiographic equipment by developed software for phantom images

Mayo Nogueira, Patricia; Ródenas Escribá, Francisco de Asís; Campayo, J. M.; Marin, B.; Verdú Martín, Gumersindo Jesús (American Nuclear Society, 2011)

[EN] The assessment and control of image quality is a fundamental task associated with good practice to guarantee a suitable diagnosis by the radiologist. The need for image quality assessments in radiography is well ...
Recent advances and applications of hyperspectral imaging for fruit and vegetable quality assessment

Lorente, D.; Aleixos Borrás, María Nuria; Gómez Sanchís, Juan; Cubero, S.; García Navarrete, Óscar Leonardo; Blasco Ivars, José (Springer Verlag, 2011-05)

[EN] Hyperspectral imaging systems are starting to be used as a scientific tool for food quality assessment. A typical hyperspectral image is composed of a set of a relatively wide range of monochromatic images corresponding ...
Through-focus response of multifocal intraocular lenses evaluated with a spatial light modulator

Remón Martín, Laura; Arias, Augusto; Calatayud Calatayud, Arnau; Furlan, Walter Daniel; Monsoriu Serra, Juan Antonio (Optical Society of America, 2012-12-20)

A new testing technique based on the use of a liquid crystal spatial light modulator (SLM) is proposed to analyze the optical quality of multifocal intraocular lenses (MIOLs). Different vergences and decentrations of the ...
Workshop on reconstruction schemes for magnetic resonance data: summary of findings and recommendations

Ozturk-Isik, Esin; Marshall, Ian; Filipiak, Patryk; Benjamin, Arnold J. V.; Ones, Valia Guerra; Ortiz-Ramón, Rafael; Valdes Hernandez, Maria del C. (The Royal Society, 2017)

[EN] The high fidelity reconstruction of compressed and low-resolution magnetic resonance (MR) data is essential for simultaneously improving patient care, accuracy in diagnosis and quality in clinical research. Sponsored ...
