In Vivo Detection of the Injection of Normal Saline in Rabbit's Abdomen Using Magnetic Induction Tomography
摘要
Abstract
Objective Our study aimed to investigate the feasibility of magnetic induction tomography (MIT) detecting the conductivity distributionin vivo.Methods A model of injecting normal saline into rabbit's abdomen was established. The time-difference Newton-Raphson algorithm was applied to obtain the reconstructed images based on the background frames of conductivity distribution before injection by a 16 excitation-detection multiplex coils system. Statistical correlation and the significant differences between reconstructed values and doses were subsequently analyzed.Results The reconstructed images showed the position of the saline injection, whose reconstructed values up-regulated with the dose increasing and were linearly dependent with dose.Conclusion MIT is available to investigate conductivity distributionin vivo by detecting the position and the variation trend of reconstructed values exactly with injected dose.关键词
