Abstract
A method and a device for visually assisting a catheter application on the heart of a patient using an image of the patient obtained by a C-arm X-ray device and using electroanatomical mapping data of the patient obtained by an electromagnetic position detection system and mapping system. The C-arm X-ray device and the electromagnetic position detection system and mapping system are calibrated in relation to each other, by determining a co-ordinate transformation between a co-ordinate system assigned to the C-arm x-ray device and/or a co-ordinate system assigned to the image generated by the C-arm X-ray device and a co-ordinate system assigned to the electromagnetic position detection system and mapping system. The position of the patient is determined during the detection of the image and/or during the detection of the electroanatomic mapping-data and is at least indirectly assigned to the image and/or the electroanatomic mapping-data.

57. A method for visually assisting a catheter application on a heart of a patient, comprising:
-
acquiring an image of the patient by a C-arm X-ray device; acquiring electroanatomical mapping data of the patient by an electromagnetic position-detection and mapping system; determining a coordinate transformation between a coordinate system of the C-arm x-ray device and a coordinate system of the electromagnetic position-detection and mapping system; calibrating the C-arm X-ray device and the electromagnetic position-detection and mapping system in relation to each other based on the coordinate transformation; determining a position of the patient during the acquisition of the image and the acquisition of the electroanatomical mapping data; and assigning the position of the patient to the image and the electroanatomical mapping data. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75)

76. A device for visually assisting a catheter application on a heart of a patient, comprising:
-
a C-arm X-ray device that acquires an image of the patient; an electromagnetic position-detection and mapping system that acquires electroanatomical mapping data of the patient; and a computing device that; determines a coordinate transformation between a coordinate system of the C-arm x-ray device and a coordinate system of the electromagnetic position-detection and mapping system, calibrates the C-arm X-ray device and the electromagnetic position-detection and mapping system in relation to each other based on the coordinate transformation, determines a position of the patient during the acquisition of the image and the acquisition of the electroanatomical mapping data; and assigns the position of the patient to the image and the electroanatomical mapping data.
