Abstract

UN ELEMENTO PARA LA FORMACION DE IMAGENES EFECTUA LA CARACTERIZACION DE LA MORFOLOGIA DE UN TEJIDO ANALIZANDO MODELOS DE PERFUSION DE UN MEDIO DE CONTRASTE EN EL TEJIDO VISUALIZADO POR EL ELEMENTO PARA LA FORMACION DE IMAGENES, PARA IDENTIFICAR TEJIDO INFARTADO. EN UNA IMPLEMENTACION PREFERIDA, UN TUBO DE CATETER (12) INTRODUCIDO DENTRO DE UNA REGION DEL CORAZON LLEVA EL ELEMENTO DE FORMACION DE IMAGENES (34), ASI COMO UNA ESTRUCTURA DE SOPORTE (20) SEPARADA DEL ELEMENTO DE FORMACION DE IMAGENES, QUE CONTRAE LOS TEJIDOS ENDOCARDIALES. EL ELEMENTO PARA LA FORMACION DE IMAGENES SE MUEVE A MEDIDA QUE EL ELEMENTO PARA LA FORMACION DE IMAGENES VISUALIZA EL TEJIDO. SE DETECTA UN EVENTO ELECTRICO SELECCIONADO EN EL TEJIDO CIRCUNDANTE DEL MIOCARDIO QUE REGULA EL MOVIMIENTO DEL ELEMENTO PARA LA FORMACION DE IMAGENES. EL ELEMENTO DE SOPORTE ESTABILIZA EL MOVIMIENTO DEL ELEMENTO PARA LA FORMACION DE IMAGENES A MEDIDA QUE VISUALIZA EL TEJIDO, SUMINISTRANDO RESISTENCIA AL DESALOJO O A LA DESORIENTACIONA PESAR DE LA PRESENCIA DE FUERZAS DINAMICAS.
