Abstract

BACKGROUND

In recent years the visualization of biomagnetic measurement data by so-called pseudo current density maps or Hosaka-Cohen (HC) transformations became popular.

METHODS

The physical basis of these intuitive maps is clarified by means of analytically solvable problems.

RESULTS

Examples in magnetocardiography, magnetoencephalography and magnetoneurography demonstrate the usefulness of this method.

CONCLUSION

Hardware realizations of the HC-transformation and some similar transformations are discussed which could advantageously support cross-platform comparability of biomagnetic measurements.

摘要

背景

近年来，通过所谓的伪电流密度图或保坂 - 科恩（HC）变换来可视化生物磁测量数据变得流行起来。

方法

借助可解析求解的问题来阐明这些直观图的物理基础。

结果

在心电图、脑电图和神经电图方面的实例证明了该方法的实用性。

结论

讨论了HC变换及一些类似变换的硬件实现方式，它们能够有利地支持生物磁测量的跨平台可比性。
