| Research Abstract |
For mammography using the scattered radiation, I went the development of new technology to improve of image resolution, to improve of detectionsensitivity of Ca image, to reduce exposure. (1) Optical properties reading technique, by using artificial intelligence. (2) Information extraction spatial filter. (3) Two-step energy subtraction process. (4) Scattering angle subtraction method. (5) Spatial frequency domain subtraction. However, these are not possible to overcome the problem occurring in each of the new technology, these have not been put to practical use.
