Paper Abstract
The aim of this study was to conduct a preliminary check of a new method for measuring the 3D catheter
position based on only one X-Ray view (image) and a simple pre-calibration procedure for catheters that
could be equipped with high-opacity equal-spaced markers. The application chosen for this experiment is the
targeted delivery of cell based therapeutic via a transendocardial retrograde approach into the left ventricle.
This approach has shown promising therapeutic retention data when injected directly into the myocardial
tissue, but lacks in the ability of the user to confidently manipulate the catheter within the left ventricle cavity
space under traditional fluoroscopic guidance using a needle based catheter. The need for a new technique
arose from the potential for increased safety and therapeutic efficacy by improving the targeting of the agent.
The new technique, destined for Image guided catheter navigation systems for cardiac interventions, is based
on a measurement of the marker's size and distance between them and followed by a comparison with the
referenced catheter position. Preliminary experiments made with a simple phantom are presented,
emphasizing the ability of the new technique in measuring the markers and the catheter tip 3D position. An
overall maximum error in positioning markers and catheter tip below 12% has been obtained, yielding a
promising result for continuing the future work of improving the algorithm accuracy.
