Summary
We improved the originally reported synchrotron radiation (SR) micro-angiographic system by applying avalanche-type high-definition (HD) video camera. The New Super Harp HDTV (NHK, Tokyo) with high contrast resolution and effective quantum ratio of 640 allowed precise assessment of configuration of small vessels (less than 100 mm after digital processing) in heart, brain, and the other organs. The originally used image-intensifier-video camera system could not delineate small vessels well. Conventional HD video system using CCD could not reveal small vessels of heart and brain in situ. This system would allow us clinical evaluation of small vessel -diseases in heart, brain, and the other organs and also visualization of newly developed small vessels due to angiogenesis in malignant tumor and circulatory disorders.
