| dc.description.abstract | Para obtener la parte real del espectro de impedancia se diseño un sistema de detección sincrona que permite extraer esta información a partir de la amplitud de la tensión medida y la fase entre las señales de tensión y corriente. Un último modulo es el encargado de la adquisición de datos y comunicación con el PC. Se implemento un programa en Labview7.1 que permite realizar un barrido automático de las frecuencias programadas* y a la vez adquirir la señal de tensión que posee la información de la parte real de la impedancia del tejido. Es posible visualizar la parte real del espectro de impedancia eléctrica en tejido cervicouterino y los valores de impedancia a cada una de las frecuencias. El software genera reportes con los datos personales de las pacientes y los resultados de la medición. El rango de medición de impedancia del equipo se encuentra entre 6m-m y 25-m. Las mediciones de la parte real de impedancia eléctrica en tejido cervicouterino obtenidas se ajustaron al modelo Cole-Cole, empleando el algoritmo desarrollado por Miranda**, el cual proporciona los parámetros , , ,0RRy el error cuadrático medio | |
| dc.description.abstractenglish | This document describes to the design and implementation of a prototype forapplications of electrical impedance spectroscopy, the results of measurementsmade in cervical tissue In-Vitro and its adjustment to the Cole-Cole model. A prototype was designed to able to measure the real part of the electricalimpedance spectrum, by means of a injection current system multifrequencyconfigured to operate to seven frequencies within the interest range (10kHz,20kHz, 40kHz, 80kHz, 160kHz, 320kHz, 640kHz). In order to obtain the real part of the electrical impedance spectrum, asynchronous detection system was designed to allow to extract this informationfrom the amplitude of the measured voltage and the phase between the voltageand current signals. A last one part is in charge of getting data acquisition andcommunicating with the PC. A program was implemented in Labview7.1 which allows to make an automaticsweeping of the programmed frequencies ° and simultaneously to acquire thevoltage signal that has the information of the real part of the electricalimpedance spectrum. It is possible to visualize the real part of the electricalimpedance spectrum in cervical tissue and the impedance values to each oneof the frequencies. Software generates reports with the personal data of thepatients and measurement results. The range of impedance measurementequipment is between 6MQO-m and 250-m. The obteined measurements of the real part of the electrical impedancespectrum in cervical tissue was adjusted to the Cole-Cole model, using thealgorithm developed by Miranda , which provides the parametersa, t, R,, R,, and the quadratic error average. "These values of frequency were selected for aims of the present work, but any group of frequencies in the range between 1kHz and1MHz can be programmed“* Software developed in the | |
