Abstract
Particle accumulations in the lungs can be detected because of their external magnetic characteristics. With this principle as a basis, equipment for measuring the magnetic field emanating from the lungs was developed that is capable of ascertaining the quantity and distribution of particles lodged in the lungs. However, because there are some errors of measurement, accurately determining the amount and distribution of particles is still difficult. We previously reported results obtained in a model test. We conclude here that the quantity and distribution of particles lodged in the lungs from the surface to the inner region can be ascertained by performing a surface elimination of magnetism.
