A spectroscopic paradigm has been developed that allows the magnetic field emissions generated by the electrical activity in the human body to be imaged in real time. The growing significance of imaging modalities in biology is evident by the almost exponential increase of their use in research, from the molecular to the ecological level. The method of analysis described here allows totally noninvasive imaging of muscular activity (heart, somatic musculature). Such imaging can be obtained without additional methodological steps such as the use of contrast media.

已经开发出一种光谱学范例，可以实时成像人体电活动产生的磁场发射。成像模式在生物学中的重要性日益增加，从分子水平到生态水平，它们在研究中的使用呈指数级增长。这里描述的分析方法允许对肌肉活动（心脏、躯体肌肉）进行完全非侵入性成像。无需使用造影剂等额外的方法步骤即可获得这种成像。
