Abstract

Système de simulation d’examen par cathéter pour apprendre un état de détection de bioinformation détectée pendant un examen par cathéter. Un simulateur de cathéter (2) comprend un modèle d’organe (14) simulant un organe et des caméras CCD (28, 29) pour créer l’image du modèle d’organe (14). Dans un dispositif de simulation (38), une section de création de simulation d’électrocardiogramme intracardiaque (42) référence une section de stockage de données d’électrocardiogramme intracardiaque (41) et crée une simulation d’électrocardiogramme intracardiaque correspondant à l’information de position sur un cathéter (51) déterminée par une section de détermination de position de modèle intra-organique sur le cathéter (40). Une section de création de simulation d’image par rayon X (44) référence une section de stockage de données d’image par rayon X (43) et crée une simulation d’image par rayon X correspondant à l’information de position déterminée sur le cathéter (51). Une section d’affichage (49) affiche à l’écran la simulation d’électrocardiogramme intracardiaque, la simulation d’image par rayon X et des images du modèle d’organe (14) capturées par les caméras CCD (28, 29).
