Here it is shown that the actual data have a dependent property, which is called the redundancy of the projection data. It is shown that the redundancy is effective for the reduction of the noise sensitivity of the reconstruction formula. This paper evaluates the effect qualitatively and experimentally in comparison with the convolution method, which is the mainstream of the present reconstruction procedure. The reconstruction formula (formula II), which was derived in a previous paper to reduce the noise sensitivity utilizing the redundancy, is compared with the convolution method. The analytical comparison with the mean\u2010square error as the evaluation measure, as well as the visual comparison of the actually reconstructed examples, are performed.<\/jats:p>","DOI":"10.1002\/scj.4690170309","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T11:23:19Z","timestamp":1183807399000},"page":"75-83","source":"Crossref","is-referenced-by-count":0,"title":["Availability of redundancy of projection data applied to reduce the noise sensitivity of reconstructed images"],"prefix":"10.1002","volume":"17","author":[{"given":"Itsuo","family":"Kumazawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taizo","family":"Iijima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"3","article-title":"A new theory for image reconstruction for computed tomography","volume":"64","author":"Tijima T.","year":"1981","journal-title":"Trans.
