Abstract

Current density and electrical conductivity imaging research at the University of Toronto is reviewed. Methods for imaging live animals at low frequency are described and contrasted with EIT and other MRI based techniques. New work on imaging at radio frequencies is presented and future work directions are discussed. It is concluded that low frequency methods are mature and ready for application in small animals and that radio frequency methods will soon have application in small animals.

摘要

本文综述了多伦多大学的电流密度和电导率成像研究。描述了低频下对活体动物成像的方法，并将其与电阻抗断层成像（EIT）和其他基于磁共振成像（MRI）的技术进行了对比。介绍了射频成像方面的新工作，并讨论了未来的工作方向。得出的结论是，低频方法已经成熟，可应用于小动物成像，而射频方法也将很快应用于小动物成像。
