The latitudinal size of the x\u2010ray tube focal spot was . The detector dimension was 1824 channels rows (longitudinal direction) at row width of , in which a thinner reflected separator surrounds each detector cell coupled with a large active area photodiode. They were mounted on a commercial 64\u2010slice CT scanner gantry while the scan field of view and gantry rotation speed can be maintained. The experimental CT scanner demonstrated the spatial resolution of with the acrylic slit phantom and in\u2010plane 50%\u2010MTF and 10%\u2010MTF . In the longitudinal direction, it demonstrated the spatial resolution of with the high\u2010resolution insert of the CATPHAN phantom and as the full width at half maximum of the slice sensitivity profile. In low\u2010contrast detectability, at 0.3% was visualized at the of . Two types of diameter vessel phantoms with in\u2010stent stenosis at 25%, 50%, and 75% stair steps were scanned, and the reconstructed images can clearly resolve the stenosis at each case. The experimental CT scanner provides high\u2010resolution imaging while maintaining low\u2010contrast detectability, demonstrating the potentiality for clinical applications demanding high spatial resolution, such as imaging of inner ear, lung, and bone, or low\u2010contrast detectability, such as imaging of coronary artery.<\/jats:p>","DOI":"10.1118\/1.3086117","type":"journal-article","created":{"date-parts":[[2009,3,31]],"date-time":"2009-03-31T07:55:42Z","timestamp":1238486142000},"page":"1120-1127","source":"Crossref","is-referenced-by-count":21,"title":["Development and performance evaluation of an experimental fine pitch detector multislice CT scanner"],"prefix":"10.1002","volume":"36","author":[{"given":"Yasuhiro","family":"Imai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masatake","family":"Nukui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yotaro","family":"Ishihara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Fujishige","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Ogata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Moritake","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haruo","family":"Kurochi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Ogata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuru","family":"Yahata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangyang","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,3,11]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031\u20109155\/50\/16\/016"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031\u20109155\/51\/4\/007"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.598473"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.215.1.r00ap3755"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.1949787"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.2722872"},{"key":"e_1_2_6_8_1","first-page":"1417","article-title":"Experimental flat\u2010panel high\u2010spatial\u2010resolution volume CT of the temporal bone","volume":"25","author":"Gupta R.","year":"2004","journal-title":"AJNR Am.
