Abstract PROBLEM TO BE SOLVED: To provide a three-dimensional (3D) electrical mapping system and method.SOLUTION: A 3D electrical mapping system and method may be used to generate a 3D image of the epicardial surface of a heart by integrating one or more epicardial images with a 3D image of the cardiac structure that may be generated by a real-time 3D location and mapping system for cardiac mapping and ablation. The visual textural representation of the epicardial surface of the heart may be reconstructed using an image sensor or camera-based catheter to collect images of the epicardial surface. For each image that is captured, the system and method may store the image data along with the corresponding catheter location, orientation and/or distance information relative to the cardiac structure. The location, orientation and/or distance information may be used to reconstruct a 3D textural model of the epicardial surface of the cardiac structure.SELECTED DRAWING: Figure 2A 【課題】 三次元(3D)電気的マッピングシステム及び方法を提供すること。【解決手段】 3D電気的マッピングシステム及び方法は、1つ以上の心外膜画像を、心臓マッピング及びアブレーションのためのリアルタイム3D位置特定及びマッピングシステムによって生成され得る心構造の3D画像と統合することによって、心臓の心外膜表面の3D画像を生成するために用いられ得る。心臓の心外膜表面の視覚的テクスチャ表現は、心外膜表面の画像を収集するための画像センサ又はカメラ式カテーテルを用いて再構成され得る。キャプチャされる各画像に対して、システム及び方法は、画像データを、対応する、心構造に対するカテーテルの位置、向き、及び/又は距離に関する情報と共に格納し得る。位置、向き、及び/又は距離に関する情報は、心構造の心外膜表面の3D組織モデルを再構成するために用いられ得る。【選択図】 図2A
