Method and device for visually supporting an electrophysiology catheter application in the heart

摘要

#CMT# #/CMT# A heart catheter visual support procedure displays (6, 13) electroanatomical 3D (Three Dimensional) mapping (15) from markers placed on the rib cage with segments (11) of a previously obtained tomographic image (14) in correct dimensional relationship (12) as a polygon network using a volume rendering technique with adjustable transparency and blending (7) factor. #CMT# : #/CMT# Independent claims are included for equipment using the procedure with images from X ray, or magnetic resonance tomography or ultrasonic imaging and for subsequent refinement stages using surface matching and calculation of the relative catheter tip position (16). #CMT#USE : #/CMT# Visual support procedure for heart catheter operations including catheter ablation. #CMT#ADVANTAGE : #/CMT# Provides more accurate orientation of catheter guidance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing is a block diagram of the equipment using the procedure.
