Abstract
La Ingeniería Biomédica es posiblemente, junto con las tecnologías de la información y la comunicación, uno de los campos tecnológicos de mayor crecimiento en los últimos años. Así mismo, la imagen médica para la investigación es un elemento de gran importancia dentro de este campo. En este trabajo se pretende dar solución a un problema con el que se enfrenta la imagen médica cuando el objeto de estudio es el corazón. Al ser un órgano que se encuentra en constante movimiento, y que este movimiento es involuntario, la imagen médica del corazón presenta problemas, artefactos y emborronamiento.
La técnica de imagen sincronizada con el ciclo cardíaco es una solución factible para el mencionado problema. Para ello es indispensable conocer el movimiento que se produce en el corazón en cada instante, y esto a su vez es posible gracias al electrocardiograma (ECG).
En este trabajo se desarrolla e implementa un electrocardiógrafo, que además de monitorizar la señal cardíaca puede generar una señal de sincronismo para indicar a la máquina de imagen utilizada que debe comenzar la adquisición.
Para ello, se han seleccionado los elementos electrónicos adecuados, se ha estudiado su funcionamiento, y se ha programado el sistema, además de haber adquirido conocimientos sobre la señal de ECG.
Biomedical Engineering is probably one of the most rapidly growing technologic fields in the last years. In adition, medical imaging for research is a very important element within this field. This work order degree aims to solve a problem medical imaging has to face when the heart is the subject of study. As far as this organ is in constant movement and this movement is involuntary, medical image of the heart shows problems, artifacts and blurring. Electrocardiogram (ECG)-gated technique is a valid solution for the mentioned issue. In order to apply this technique it is necessary to know the movement of the heart at every moment, and this is posible thanks to the electrocardiogram. This Project develops and implements an electrocardiograph that is able to monitorize the cardiac signal and generate a gating signal, to indicate to the medical imaging machine that data aquisition should start. To achieve this goal electronic devices have been selected, studied and programmed. It has also been necessary to aquire some knowledge about the ECG.
