VECTOR FIELD TOMOGRAPHY APPARATUS AND VECTOR FIELD TOMOGRAPHIC IMAGE RECONSTITUTION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a tomographic image not of a scalar field such as density but of a vector field such as magnetism in the Computerized Tomography Method (CT method) for capturing a tomographic image of a specimen by utilizing electromagnetic waves of X rays or the like, electron beams, or corpuscular beams such as neutron beams.SOLUTION: From x-&phgr; distribution of an intensity I(x) which is measured by rotating a specimen or incident energy rays by &phgr;, 2I(x) cos(&phgr;) and 2I(x) sin(&phgr;) is used to reconstitute a sinogram and component separation of a vector field is performed for reconstitution, thereby obtaining a tomographic image of a vector.
