Abstract

Noninvasive Imaging of the bioelectric processes on the heart using Electrocardiography (ECG) and Magnetocardiography (MCG) data is a widely discussed research topic of the recent years. The source space of ECG is compared with the source space of MCG and vice versa to investigate the difference of information content of these mapping techniques for source imaging purposes. The approach allows the calculation of the intersection and non-intersection part (the calculation of silent sources) of MCG (ECG) in comparison to ECG (MCG). The investigation was carried out on a Finite Element model which was constructed from a magnetic resonance imaging (MRI) dataset of a volunteer. Anisotropic fibre orientation was applied to myocardium to investigate its effect on the differences of the source spaces.

各向同性和各向异性胸腔模型的心电图和心磁图源空间研究
利用心电图(ECG)和心磁图(MCG)数据对心脏的生物电过程进行无创成像是近年来广泛讨论的研究课题。将心电信号的源空间与心电信号的源空间进行对比,并将心电信号的源空间与心电信号的源空间进行对比,探讨两种源成像成像技术在信息含量上的差异。该方法可以计算出与ECG (MCG)相比较的MCG (ECG)的相交部分和非相交部分(无声源的计算)。这项研究是在一个有限元模型上进行的,该模型是由一个志愿者的磁共振成像(MRI)数据集构建的。将各向异性纤维取向应用于心肌,探讨其对心肌源空间差异的影响。
