ABSTRACT

A multichannel measuring system for magnetic induction tomography has been developed. Oscillating magnetic field is applied in the system as sounding agent. The device enables non-contacting visualization of the conductivity distribution inside the objects under investigation. The measurements on the saline filled phantoms have been carried out and corresponding images have been reconstructed using the weighted filtered back-projection algorithm. Development of static image reconstruction algorithms is the issue of the day. Application of artificial neural networks for solving this problem is demonstrated. The results of the research demonstrate wide perspectives for the application of the magnetic induction tomography in medicine and biomedical researches. Industrial applications are suggested also.
