| 摘 要： | 利用非线性反演问题中所采用的模拟退火算法，建立了基于脑磁图反演脑内作为磁源的电流偶极子的模型。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，尚有待进一步研究。

| Abstract: | 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. |
