Abstract:
1. A method for visualizing at least one section of a wall of an atrium of the heart in a patient after an ablation for treatment of atrial fibrillation and based on a volume data record of the heart in the patient obtained after the ablation, the method comprising: segmenting the volume data record of at least the treated atrium of the heart in the patient to establish voxels which are of an inner surface, an outer surface, and a volume situated between the inner and outer surfaces of the wall of the treated atrium; and performing volume rendering or ray casting on the at least one section of the wall of the treated atrium of the heart using only voxel values of established voxels lying on the inner surface in the volume or on the outer surface of the wall of the treated atrium, to visualize the at least one section of the wall of the treated atrium of the heart, wherein, during the volume rendering or ray casting, at least one of wherein only the voxel values from the voxels impinged by at least one of the beams and that lie on the inner surface in the volume or on the outer surface of the wall of the treated atrium are used for establishing a beam value.
