基于混合测量模式的电阻抗图像融合方法
A Novel Electrical Impedance Image Fusion Method Based on Hybrid Measurement Pattern
摘要
Abstract
The soft-field properties of electrical impedance imaging and the indefinability of its inverse problem solving will cause artifacts in the image and produce the problem of low spatial resolution.For this issue,a novel electrical impedance image method based on hybrid measurement pattern is proposed in the current study.In the 16-electrode electrical impedance data acquisition system,the boundary voltage was first measured according to the working mode of adjacent excitation and adjacent measurement,and the total variation or Tikhonov regularization algorithm imaging was obtained.Then,8 electrodes were selected,their boundary voltages were measured,and the images were obtained by the same imaging algorithm.The two images were weighted and fused,and the weight parameters were determined by the objective weighting method.At the same time,the analytic hierarchy process subjective weighting method was used to transform the three image quality evalu-ation indexes of relative error,correlation coefficient and structure similarity index measure into a comprehensive evaluation index F,which was used to evaluate the image quality obtained by the method.The method was validated by taking bladder electrical impedance imaging as an example.The results show that F value is increased by 4.78%-79.00%after the proposed method,which indicates the effectiveness and feasibility of the proposed method.This article provides a new method for improving the quality of electrical impedance images.关键词
