This thesis presents the Magneto-Acousto-Electrical Tomography (MAET) with magnetic field measurements technique with an experimental study, which is also supported by 2D numerical simulations. The very aim of this method is to exploit the conductivity distribution of human tissues as tomographic images and this thesis attempts to demonstrate the feasibility of this technique by obtaining measurements from the magnetic coil sensors placed around the object to be imaged. For this purpose, the mathematical foundation of MAET is integrated into a custom-built tomographic imaging simulation model which solves the coupled partial differential equations for the MAET forward and reciprocal problems. Measurements from 11 magnetic coil sensors placed around a phantom object are obtained to reconstruct the image in these simulations. Furthermore, MAET experiments are conducted on an object mimicking the properties of human breast under 0.5T and 1.5T static magnetic field. Magnetic field measurements are obtained from the coils placed around this phantom and the measurements are correlated with the simulation results. The results exhibit the effectiveness of MAET using magnetic field measurements as a tomographic imaging method in discriminating the tissue boundaries close to human tissue conductivity values for the first time in literature.
