Abstract
A catheter tracking system for visualization of fluoroscopic images, the system comprising a fluoroscope for generating fluoroscopic image data, a fluoroscopic image visualization monitor, a catheter having an elongated shaft, particularly an intraventricular catheter, distal tip and a radio opaque portion adjacent the distal tip. A circumferential radio opaque band may be used to determine the relative position, orientation and motion of the catheter. An image analysis system capable of analyzing the image of the catheter and the radio opaque band, for receiving fluoroscopic image data from the fluoroscope determining physical parameters related to the left ventricle, and the relative position, orientation and motion of the catheter therein, and for determining the location and other parameters of treatment on intraventricular surfaces.
