Abstract

X-ray CT system with phase-contrast and fluorescent techniques are being developed for biomedical researches. We have applied these techniques for in-vivo and ex-vivo imaging. The phase-contrast x-ray CT enables to reveal the detailed morphological information of cancer lesion, and image quality of ex-vivo specimen was excellent comparing to 4.74T micro-MRI. Fluorescent x-ray CT could depict the functional information with high spatial resolution, and its image quality was almost the same as autoradiogram. Improvement of imaging system with much high-speed data acquisition will enable to use these techniques for new biomedical researches.
