一种新型的用于电磁层析成像系统中图像可信度估计的统计方法

For Electromagnetic Tomography (EMT) Techniques, image reconstruction is one of the crucial steps. For previous works, two criteria, namely the relative image error and correlation coefficient, were often used to evaluate reconstruction quality, but the measurement uncertainty, which exists in the process of obtaining inductance measurements and sensitivity maps, wasn't taken into account. In this paper, a statistical index was proposed for the first time to quantitatively evaluate the image confidence level for each pixel of the reconstructed image through error propagation analysis.
