ANN Interpolation in MCG Mapping

Magnetocardiogram is a kind of medical image based on measuring the weak magnetic field of human heart, which reflects the magnetic activity in the human heart, and provides diagnosis information of heart diseases. At present, before visualizing the map based on very limited data, it should be pretreated through interpolation. To gain the high precision, we researched the interpolation in MCG and proposed a new method to solve it - ANN interpolation. Then we analyzed the performance among ANN interpolation, cubic spline interpolation and linear interpolation. The result is that ANN interpolation can reach the acquirement
