英文摘要	We introduce a general iterative scheme for angle-limited image reconstruction based on Landweber's method. We derive a representation formula for this scheme and consequently establish its convergence conditions. Our results suggest certain relaxation strategies for an accelerated convergence for angle-limited image reconstruction in L (2)-norm comparing with alternative projection methods. The convolution-backprojection algorithm is given for this iterative process.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000264259400015&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Mathematics, Applied; SCI(E); 中国科学引文数据库(CSCD); 5; ARTICLE; 2; 327-334; 25
