球模型下MEG正问题的计算

Calculation of MEG Forward Problem in Centrosphere Head Model

主要对MEG正问题进行讨论.即在非均匀的有界导体模型下建立求解脑外磁场B珗的计算公式,并以离散的偶极子源模型来近似电流源,进一步考察球对称导体下磁场的简便计算.

This paper focused on the MEG. The uniform bounded conductor model was established for brain magnetic field calculation formula; and to the discrete dipole approximation current source, further investi- gation of spherically symmetric conductor was carried out under a magnetic field calculation.
