--- abstract: "We present a neural network approach for tomographic imaging problem using interpolation methods and fan-beam projections. This approach uses a partially connected neural network especially assembled for solving tomographic\r\nreconstruction with no need of training. We extended the calculations to perform reconstruction with interpolation and to allow tomography of fan-beam geometry. The main goal is to aggregate speed while maintaining or improving the quality of the tomographic reconstruction process." altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - lfm@egc.ufsc.br - hsilva@facinter.br - edu@eletrica.ufpr.br creators_name: - family: Medeiros given: Luciano Frontino de honourific: '' lineage: '' - family: Silva given: Hamilton Pereira da honourific: '' lineage: '' - family: Ribeiro given: Eduardo Parente honourific: '' lineage: '' date: 2003 date_type: published datestamp: 2008-06-13 00:08:41 department: ~ dir: disk0/00/00/60/85 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 6085 fileinfo: /style/images/fileicons/application_pdf.png;/6085/1/artigo5.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'tomography, reconstruction, neural network, fan-beam, interpolation' lastmod: 2011-03-11 08:57:07 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 2 pagerange: 122-130 pubdom: FALSE publication: Learning and Nonlinear Models – Revista da Sociedade Brasileira de Redes Neurais publisher: ~ refereed: TRUE referencetext: "[1] M.T.
