基于FPGA的高性能三维电阻抗成像系统
FPGA-Based 3D High-Performance Electrical Impedance Tomography System
摘要
Abstract
A set of 3D FPGA-based high-performance electrical impedance tomography(EIT)system with two-layer 32 electrodes is designed and introduced. The software and hardware are developed and tested through experiments. The images are reconstructed by conjugate gradient(CG)algorithm. The results indicate that the average accuracy of the 3D EIT system can reach 0.082%,the spatial resolution can reach 0.51%and SNR is 60.3 dB. The imaging experiments of organic glass rods are carried out in an lab-made tank filled with saline and the images can accurate⁃ly display the number of rods and their positions and shapes. Consequently,the research lay a firm foundation for the further study on 3D electrical impedance tomography.关键词
