High spatial resolution CT with a synchrotron radiation system.
OBJECTIVE
We describe a monochromatic X-ray CT system using synchrotron radiation, which has been constructed employing a vertical wiggler beam line at the National Laboratory for High-Energy Physics in Tsukuba, Japan. This CT system was produced to facilitate examination of the microstructures of material and biological specimens.


METHODS
The system provides excellent contrast and has a spatial resolution capacity ranging from 2 to 100 mm. In this preliminary experiment, the images of the rat were obtained at 36-mm slice thickness and 33.2-keV X-ray energy.


RESULTS
The nasal cartilage, skull, and teeth of a live rat were clearly demonstrated with 36-mm spatial resolution.


CONCLUSIONS
Using a monochromatic X-ray CT system with synchrotron radiation, detailed structures of rat skull were imaged clearly.
