Study of medical imaging of X-ray minute point source using synchrotron radiation

1.利用平行x射线束吸收成像计算微血管造影的辐射剂量。这些结果发表在《放射医学》杂志上。提出了一种检测x射线成像边缘的诺贝尔方法。研究结果发表在《igakubutsuri》杂志上。平行x射线束观察成骨细胞、成骨细胞及骨组织精细结构。这些结果发表在《放射医学》杂志上。开发了用x射线追踪法评估障碍物对比度的仿真程序。对比了折射成像与吸收成像的差异。这些结果发表在《放射医学》杂志上。5 .采用针刺法进行影像学实验。模拟了重叠障碍物折射模式的干扰。该方法计算了散斑图案的形成条件。这些结果发表在《放射医学》杂志上。

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.
