Measurement of the magnetic fieldsof the lung, called magnetopneumogrphy, provides a good tool for those engaged in lung research. The distribution of accumulated particles in the lung, however, is not accurately reflected by a measurement value for magnetic flux density alone. Actually, it is necessary to determine the distribution of particles in the lung quantitatively to be able to apply results for clinical use. To estimate the distribution and amount of magnetic dipoles, we used a spatial filter to reduce noise in the measurement values. An analytical result by the least squares method is provided that uses a method for removing the noise included in the measurement values with a spatial filter. This analysis method is called magnetic noise elimination.
