New developments in instrumentation, in clinical application, as well as in data analysis and visualization have provided new momentum to magnetocardiography (MCG). On one hand robust, easy to use and budget-priced MCG-systems entered the market and are applied to a multi-centred clinical study. On the other hand highly sophisticated vectormagnetometer systems with >300 SQUID sensors are opening new perspectives in electrocardiology research. Several parameters have recently been introduced to evaluate MCG-signals in order to support diagnosis, therapy follow-up and risk stratification. Particularly interesting is the renaissance of the Hosaka-Cohen-transformation which allows to visualize so-called pseudo current density (PCD) maps. A few examples are given to emphasise the value of these maps.
仪器设备、临床应用以及数据分析与可视化方面的新进展为心磁图（MCG）带来了新的发展动力。一方面，坚固耐用、易于使用且价格实惠的MCG系统进入市场，并应用于一项多中心临床研究。另一方面，配备超过300个超导量子干涉器件（SQUID）传感器的高度精密矢量磁力仪系统为心电学研究开辟了新的前景。最近引入了几个参数来评估MCG信号，以支持诊断、治疗随访和风险分层。特别值得关注的是霍萨卡 - 科恩变换的复兴，它能够可视化所谓的伪电流密度（PCD）图。文中给出了一些例子来强调这些图的价值。
