A monochromatized X\u2010ray using a crystal spectrometer is passed through a slit (width 25 mm, variable height 25 \u03bcm to 2.5 mm), and then irradiated on a rotating sample. The X\u2010ray passed through the sample is converted into an electrical signal by using an X\u2010ray detector with 1024 channels, and then fed into a computer input. This monochromatic X\u2010ray CT has a view field 25 mm in diameter. The CT has an X\u2010ray spectroscopy function and a direct magnifying function of projection using an asymmetrical Bragg reflection, as well as a function for conventional cross\u2010sectional images. This paper describes theoretical analyses of the spatial resolution and noise in reconstructed images which determine the capability of an X\u2010ray CT, and the experimental evaluation of the prototype CT. Theoretically, the spatial resolution is expected to be greater than 25 \u03bcm at a magnification of 5, and this agreed with experimental results, as well as the theoretically determined noise in reconstructed images. The prototype apparatus has an energy resolution of 0.1 percent (full width of half maximum) in an energy range of 7 to 40 keV. This makes an absolute\u2010value measurement of the X\u2010ray absorption coefficient possible, and this has been confirmed experimentally. By using this apparatus, it is possible to produce an image quantitatively indicating the distribution of a particular chemical element.<\/jats:p>","DOI":"10.1002\/scj.4690210810","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T19:33:29Z","timestamp":1183836809000},"page":"101-112","source":"Crossref","is-referenced-by-count":0,"title":["Monochromatic X\u2010Ray CT Using Synchrotron Radiation"],"prefix":"10.1002","volume":"21","author":[{"given":"Hideki","family":"Kohno","sequence":"first","affiliation":[]},{"given":"Hidemi","family":"Shiono","sequence":"additional","affiliation":[]},{"given":"Katsuhisa Usami,","family":"Nonmember","sequence":"additional","affiliation":[]},{"given":"Yoshio Suzuki,","family":"Nonmember","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,22]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.3327\/jnst.20.1"},{"issue":"1","key":"e_1_2_1_3_2","first-page":"165","article-title":"A shift\u2010variant decomposition for aperture correction of collimator in emission CT, experimental verification","volume":"72","author":"Pack Seungkuen","year":"1989","journal-title":"Trans.
