摘要：In this paper we develop a system for modeling and measurement of magnetic field
distributions in biological structures caused by the externally applied electromagnetic field. We
describe an effective and versatile approach for three-dimensional reconstruction of the field
distributions from two-dimensional visualization the measured magnetic field data. The finite
element model for magnetic field calculation is built. The magnetic fields of very thin slices of
the 3D object are determined and visualized. Using these 2D images as slices of 3D image and
based on the field theory and image processing techniques we developed a reconstruction
approach for 3D visualization of magnetic field. This approach combines new technologies of
3D visualizations and characterizes with flexibility, simplicity and portability. The proposed
approach was successfully applied for 3D reconstruction and visualization of magnetic field
and current distributions in biological structures. The virtual microscope is developed for
investigations of magnetic field distributions in biological structures during magnetic
stimulation. Anisotropic Magneto-Resistive (AMR) sensors are applied for magnetic field
measurements. AMR sensors are combined in array probes in order to increase productivity of
measurement process and improving the performance of probes.
