Research Abstract	Purpose: This study is how to remove disturding shadows from the tomogram. Method: Fundamental and clinical study was tested. Results: 1. In the fundamental study, a program was completed whereby blurred images were able to remove. 2. The program mentioned 1) above was further modified so that not only tomography of the circular orbit but also the program applicable to tomography of other orbits was completed. Still more, shortening of the time required for the tomogram was realized. 3. CRT was attached over the surface of the film to study feasibility of subtraction tomography in vivo.
