摘要
利用非线性反演问题中所采用的模拟退火(Sim ulated Annealing)算法,建立了基于脑磁图(MEG)反演脑内作为磁源的电流偶极子(Current-Dipole)的模型. 并根据单偶极子源的仿真实验数据,进行了反演计算,得到了较为理想的结果. 有关利用这种模型对多偶极子源的反演计算。
A model for estimating brain current dipole parameters with magnetoen\|cephalogram(MEG) is presented. In the model the simulated annealing algorithm, which is often used in nonlinear inverse problem, is adopted. Computer simulation with magnetic field measurements of a single current dipole clearly demonstrates the effectiveness of the proposed model. Whether the model could be also useful for estimating multiple current dipole parameters, will be investigated at a future date.
