Eddy Currents Distribution in Upper Extremities During Magnetotherapy

The uncertainty problem is widely analyzed in context of current density distribution. However, the aim is focused on the influence of tissue electrical properties. The main aim of article is to present the uncertainty problem in the aspect of eddy current distribution during magneto therapy of bone and muscles. The authors focused on the problem of position of conductive areas of the body relative to magnetic coil. Analyzing and considering the obtained current density with specified region of interest and referring the results to the currents induced within all tissues from which the limb is built, conclusions are very promising. Accidental change of hand position, in the wide range, gives very similar results, what is the feature of this type of applicators. In the other side, the obtained current density within the region of interest is not satisfactory against currents induced in neighboring areas. Eddy current distribution estimation is a problem itself. Results presented in paper were obtained by model basing on magnetic vector and electrical potential.
