摘要
Jacobi矩阵是电阻抗图像重建中计算量最大的部份。利用摄动法导出该矩阵的快速算法 ,可以大幅度地减少计算量。算例表明 。
The calculation of Jacobian matrixes constitutes the great mass of the calculation in image reconstruction of electrical impedance tomography. A fast algorithm of the matrix is investigated based on perturbation technique. It can reduce the calculation on a large scale. An example given here shows the effectiveness of the algorithrn. [
