Abstract :
A computed-tomography method, based on multiplane fluoroscopic imaging, was developed to reconstruct three-dimensional geometry of a multielectrode basket-catheter inside the beating heart. The method was validated in canine using intracardiac echocardiography. Geometrical imaging of a multielectrode basket-catheter using fluoroscopy is clinically feasible and can provide realistic three-dimensional electrophysiological maps of cardiac activation
