Summary: | To provide an apparatus for assessing scarring of cardiac tissue.SOLUTION: The apparatus comprises a probe and a processor. The probe has one or more electrodes, which are configured to contact the cardiac tissue at a plurality of positions and to sense respective voltages in the tissue at the positions. The processor receives the respective voltages, and computes a triangular mesh that is representative of a surface of the tissue and that comprises multiple triangles having vertices corresponding to the positions contacted by the one or more electrodes. The processor calculates respective scar areas within the triangles by comparing the respective voltages sensed at the positions corresponding to the vertices to a predefined range of the voltages that is associated with scarring, and computes a sum of the respective areas. The processor compares the sum to a total area of the triangles so as to assess a degree of the scarring of the tissue.SELECTED DRAWING: Figure 1
【課題】心臓組織の瘢痕化を評価するための装置を提供すること。【解決手段】装置はプローブ及びプロセッサで構成され、プローブは、複数の位置で心臓組織に接触し、位置における組織内のそれぞれの電圧を検知するように構成されている1つ又は2つ以上の電極を備える。プロセッサは、それぞれの電圧を受信し、組織の表面を表し、1つ又は2つ以上の電極によって接触された位置に対応する頂点を有する複数の三角形を含む、三角形の網目を計算する。プロセッサは、頂点に対応する位置で検知されたそれぞれの電圧を、瘢痕化に関連付けられている電圧の所定の範囲と比較することにより、三角形内のそれぞれの瘢痕面積を計算し、それぞれの面積の総和を計算する。プロセッサは、この総和を三角形の総面積と比較することで組織の瘢痕化の程度を評価する。【選択図】図1 |
