摘要
在心脏消融手术中,导管的定位精度决定了心脏模型的真实性和消融靶点的准确性。该文通过查阅电生理导管定位方面的文献资料,阐述了导管定位中磁电融合和干扰抑制等关键技术的实现方法。针对电定位、磁定位各自的不足之处,阐述了基于磁电融合导管定位方法的合理性,归纳并提出了磁电融合导管定位技术的总体框架:即先建立磁电转换矩阵,再结合导管形态进行优化。针对导管定位中的磁场受扰、人体移动、呼吸及心跳等干扰因素及其抑制方法进行了详细的分析和探讨。最后对三维电生理导管定位技术的发展趋势进行了展望,为基于磁电融合的导管定位技术研究提供了一些可行的思路。
In cardiac ablation procedures,the accuracy of catheter positioning determines the authenticity of the cardiac model and the accuracy of the ablation target.This article reviews the literature on catheter positioning in electrophysiology and summarizes the key technologies for catheter positioning,such as magnetic-electric fusion and interference suppression.Addressing the limitations of electric and magnetic positioning individually,the paper elaborates on the rationale for catheter positioning technology based on magnetic-electric fusion.It also outlines the framework of a complex catheter positioning system.Specifically,the magnetoelectric conversion matrix is established first,followed by the optimization of the catheter shape.The interference factors such as magnetic field interference,body movement,respiration,and heartbeat in catheter positioning and their suppression methods are analyzed and discussed in detail.Finally,the development trend of three-dimensional electrophysiology catheter positioning technology is prospected,offering feasible insights for the research on catheter positioning technology based on magnetic-electric fusion.
