| Research Abstract |
Development of visualization of human soft tissue has been performed using XDFI (X-Ray Dark-Field Imaging) that was proposed by us in 2002. Its objectives were breast, articular cartilage, carotid artery, coronary artery and iliac artery. There are two options of development; one is clinical application and the other pathological one. It will be needing to set up equipment for high contrast using phantom every day before clinical use of a system. XDFI, DEI, grating based optics have advantage of visualizing soft tissue without contrast agent over absorption contrast. They are in a strong competition. Especially XDFI has achieved imaging technique of 2D, 2.5D and 3D images. Gelatin, water and agaros were used as material of phantom. It has been proven that these can attain high contrast at 35keV. A phantom simulating human tissue is under development.
