[EN] Access to the small bowel by means of an enteroscope is difficult, even using current devices such as single-balloon or double-balloon enteroscopes. Exploration time and patient discomfort are the main drawbacks. The ...
Análisis del uso de una sonda electromagnética para el diagnóstico de cáncer colorrectal. Resultados preliminares

Nevárez Heredia, Andrea; Fornés Leal, Alejandro; Parra Escrig, Andrea; Garcia-Pardo, Concepcion; Frasson, Matteo; Pons Beltrán, Vicente; Cardona Marcet, Narciso (Sociedad Espanola de Patologia Digestiva (SEPD), 2019-11)

[ES] Múltiples avances tecnológicos se han desarrollado para optimizar la detección temprana de cáncer colorrectal, la mayoría basados en diagnóstico óptico. La diferencia de las propiedades electromagnéticas (constante ...
Análisis, desarrollo y fabricación de medios de traslación neumáticos y mejora del control electrónico del dispositivo EndoWorm

Senent Cardona, Ester (Universitat Politècnica de València, 2012-05-07)
Automatic Detection of Intestinal Content to Evaluate Visibility in Capsule Endoscopy

Noorda, Reinier; Nevárez, Andrea; Colomer, Adrián; Naranjo, Valery; Pons Beltrán, Vicente (IEEE, 2020-01-30)

In capsule endoscopy (CE), preparation of the small bowel before the procedure is believed to increase visibility of the mucosa for analysis. However, there is no consensus on the best method of preparation, while comparison ...
Automatic evaluation of degree of cleanliness in capsule endoscopy based on a novel CNN architecture

Noorda, Reinier; Nevárez, Andrea; Colomer, Adrián; Pons Beltrán, Vicente; Naranjo Ornedo, Valeriana (Nature Publishing Group, 2020-10-19)

[EN] Capsule endoscopy (CE) is a widely used, minimally invasive alternative to traditional endoscopy that allows visualisation of the entire small intestine. Patient preparation can help to obtain a cleaner intestine and ...
Design and Development of an Automatic Blood Detection System for Capsule Endoscopy Images

Pons Suñer, Pedro; Noorda, Reinier; Nevárez, Andrea; Colomer, Adrián; Pons Beltrán, Vicente; Naranjo, Valery (Springer, 2019-10-18)

Wireless Capsule Endoscopy is a technique that allows for observation of the entire gastrointestinal tract in an easy and non-invasive way. However, its greatest limitation lies in the time required to analyze the large ...
Dielectric characterization of healthy and malignant colon tissues in the 0.5 18 GHz frequency band

Fornés Leal, Alejandro; García Pardo, Concepción; Frasson, M.; Pons Beltrán, Vicente; Cardona Marcet, Narciso (IOP Publishing, 2016-10-21)

Several reports over the last few decades have shown that the dielectric properties of healthy and malignant tissues of the same body organ usually show different values. However, no intensive dielectric studies of human ...
Dielectric Characterization of In Vivo Abdominal and Thoracic Tissues in the 0.5 26.5 GHz Frequency Band for Wireless Body Area Networks

Fornés Leal, Alejandro; Cardona Marcet, Narciso; Frasson, Matteo; Castelló-Palacios, Sergio; Nevárez, Andrea; PONS BELTRÁN, VICENTE; Garcia-Pardo, Concepcion (Institute of Electrical and Electronics Engineers, 2019-03-13)

[EN] The dielectric properties of biological tissues are of utmost importance in the development of wireless body area networks (WBANs), especially for implanted devices. The early design stages of medical devices like ...
Diseño de un modelo de intestino artificial para testar dispositivos de enteroscopia

Baixauli Marín, Lucía Inmaculada (Universitat Politècnica de València, 2021-07-29)

[ES] La exploración del intestino delgado, debido a la localización y longitud de este, tiene un alto grado de dificultad y requiere de un dispositivo especial llamado enteroscopio. Este dispositivo de morfología larga y ...
