As we target higher and higher spatial resolutions, the reduced x\u2010ray focal spot size limits the temporal and contrast resolutions achievable. To overcome this limitation, in this paper we propose to use a line\u2010shaped x\u2010ray source so that many more photons can be generated, given a data acquisition interval. In reference to the simultaneous algebraic reconstruction technique (SART) algorithm for image reconstruction from projection data generated by an x\u2010ray point source, here we develop a generalized SART algorithm for image reconstruction from projection data generated by an x\u2010ray line source. Our numerical simulation results demonstrate the feasibility of our novel line\u2010source based x\u2010ray CT approach and the proposed generalized SART algorithm.<\/jats:p>","DOI":"10.1155\/2009\/534516","type":"journal-article","created":{"date-parts":[[2009,4,27]],"date-time":"2009-04-27T15:49:13Z","timestamp":1240847353000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Line\u2010Source Based X\u2010Ray Tomography"],"prefix":"10.1155","volume":"2009","author":[{"given":"Deepak","family":"Bharkhada","sequence":"first","affiliation":[]},{"given":"Hengyong","family":"Yu","sequence":"additional","affiliation":[]},{"given":"Hong","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Robert","family":"Plemmons","sequence":"additional","affiliation":[]},{"given":"Ge","family":"Wang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2009,4,27]]},"reference":[{"key":"e_1_2_7_1_2","first-page":"H166","article-title":"Computerized transverse axial scanning (tomography)\u2014part I.
