摘要
为了提高电阻抗扫描成像在检查乳腺疾病中的性能,提出一种基于静电散射模型的乳腺病灶信息提取方法。基于一个放置于初始均匀电场中的电导率常数为σ1、半径为a的球体作为乳腺癌的模型,经过一系列的公式推导,给出一个提取乳腺癌病灶参数的方法。基于边界元方法对该模型进行了数值仿真。仿真结果表明,该模型可以有效地提取乳腺癌病灶的参数信息。
In order to improve the performance of electrical impedance scanning imaging(EISI)on inspecting breast diseases,we propose a method to extract information of breast lesions based on electrostatic scattering model.Base on a sphere with conductivity constantσ1 and radius a placed in the initial uniform electric field as the model of breast cancer,we gave a method to extract the parameters of breast cancer lesions after a series of formula derivation.Based on the boundary element method(BEM),the numerical simulation of this model was carried out.The simulation results show that the model can effectively extract the parameter information of breast cancer lesions.
