摘要

摘要: 磁感應(yīng)成像(MIT)是一種利用電磁感應(yīng)原理重構(gòu)生物組織電導(dǎo)率分布的非接觸式電阻抗成像技術(shù)。該文利用亥姆霍茲線圈和20個(gè)檢測(cè)線圈搭建了旋轉(zhuǎn)式磁感應(yīng)成像系統(tǒng)，利用濾波反投影算法重構(gòu)圖像。分別利用2階和4階導(dǎo)數(shù)法峰值銳化算法處理單目標(biāo)和雙目標(biāo)檢測(cè)線圈的測(cè)量數(shù)據(jù)，通過3個(gè)客觀參數(shù)對(duì)比處理前后的重構(gòu)圖像結(jié)果。結(jié)果證明磁感應(yīng)成像中導(dǎo)數(shù)法峰值銳化能夠有效地增加圖像質(zhì)量。

Abstract: Magnetic Induction Tomography (MIT) is a contactless Electrical Impedance Tomography (EIT) technique to reconstruct the conductivity distribution of biological tissue using the principle of electromagnetic induction. In this paper, a rotating magnetic induction imaging system is constructed by using Helmholtz coil and 20 detection coils, with filtered back projection algorithm. The single target and double target detection coil measurement data are processed by the two order and four order derivative peak sharpening algorithm. The measurement data before and after processing of the reconstructed image are compared by three objective parameters. The results show that the magnetic induction imaging derivative method can effectively increase the peak sharpening image quality.
