| Outline of Final Research Achievements |
Electron tomography is realized with a transmission electron microscope, however, in general, a tomogram is distorted and affected with some artificial image due to the limited specimen tilt angle. This research work is aimed to resolve the problem by using a furthermore devised image reconstruction method as compared with the previously proposed one, namely, a unique discrete numerical method. As a result, a newly proposed method has become a powerful one to be able to reconstruct a desirable cross-section image even though the specimen object has some complex inner structures unaffected by the above mentioned problem. In principle, this characteristic can be demonstrated for a case of the small number of the projection images.
