MAGNETIC RESONANCE THERMOMETRY DURING ABLATION

Abstract

ABSTRACT Thermography of an ablation site is carried out by navigating a probe into contact with target tissue in the heart, obtaining a first position of a position sensor in the probe and acquiring a first magnetic resonance thermometry image of the 5 target tissue. The method is further carried out during ablation by iteratively read ing the position sensor to obtain second positions, and acquiring a new magnetic resonance thermometry image of the target tissue when the distance between the first position and one of the second positions is less than a predetermined dis tance. The images are analyzed to determine the temperature of the target tissue. to 1/4 IN) .. ... ..
