摘要
大脑皮层成像技术是近年出现的较有前景的脑电三维成像方法。本文通过对其成像过程物理实质的分析,提出了新的成像计算公式,使计算过程得到简化,计算精度有所提高。
During the last few years,the cortical imaging techique(CIT)was introduced and tested bynumerical and experimental tests data with very encouraging results. Thinking of the CIT as an equivalentsource technique,a new algorithm is suggested,which only use the potential formula for infinite space to complete the inward continuation. The artificial data tests show that the new algorithm is superior to the conventional algorithm for its relative simplexity and a smaller imaging error.
