5-4 Microscopic Observation of Biological Internal Structure Using Image Zooming X-ray SATICON : Imaging of Angioarchitecture of Tumor-Derived Vessels

Abstract

The synchrotron radiation microangiography system allows depiction of normal and tumor-derived small blood vessels in animal studies using 33.2keV monochromatic X-rays in an imaging mode with a field of view of 9.5mm×9.5mm. The system has been improved with respect to spatial resolution by zooming in an object; the input field of view was reduced to 4.5mm×4.5mm for higher spatial resolution imaging with resolution to 6μm for depicting tumor angiogenic small vessels in a rabbit model of cancer.
