| Research Abstract |
1.Radiation dose was calculated for microangiography by absorption imaging using parallel X-ray beam. These results were in press Radiation Medicine.
2.A Nobel method of detecting margin in X-ray imaging was invented. These results were published in Igakubutsuri.
3.Osteocyte, osteoblast and fine structure of bone tissue were observed using parallel X-ray beam. These results were published in Radiation Medicine.
4.Simulation program was developed to evaluate contrast of obstacle using X-ray tracing method. Contrasts of refraction contrast imaging were compared with those of absorption imaging. These results were in press Radiation Medicine.
5.Imaging experiment was performed using Pt.Needle.
6.Interfernce of refraction pattern of overlapping obstacles was simulated. The condition of speckle pattern was calculated in this method. These results were in press Radiation Medicine.
