Description of mapping methods using spherical splines, both to interpolate scalp potentials (SPs), and to approximate scalp current densities (SCDs). Compared to a previously published method using thin plate splines, the advantages are a very simple derivation of the SCD approximation, faster computing times, and greater accuracy in areas with few electrodes.
使用球面样条的映射方法的描述，该方法既用于插值头皮电位（SPs），也用于近似头皮电流密度（SCDs）。与先前发表的使用薄板样条的方法相比，其优点在于SCD近似的推导非常简单、计算时间更快，并且在电极较少的区域具有更高的准确性。
