Similar to micropore optics (MPO), the square matrix array of this lens contributes to the good correspondence between each individual channel and each pixel of a position-sensitive detector. The tiny difference in the curvature of each channel makes the point-spread function of this lens spatially variant. To realize image restoration of the raw data viewed through this lens, a Slice method called the Lucy-Richardson overlap-save method using total variation (LROS-TV) was used. In this work, a series of simulations were conducted to investigate at what flux and contrast levels the image features of an object can be resolved. A simple coaxial imaging experiment was also conducted to verify the LROS-TV method by changing the current of the X-ray tube from 300 to 600\u03bcA. In this paper, it was found that the slice method is suitable for image restoration of an object viewed through a polycapillary X-ray lens with square channels.<\/jats:p>","DOI":"10.3233\/faia220577","type":"book-chapter","created":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T08:03:43Z","timestamp":1671609823000},"source":"Crossref","is-referenced-by-count":0,"title":["Image Restoration of an Object Viewed Through a Polycapillary X-Ray Lens with Square Channels Using the Concept of a Space-Variant Point-Spread Function"],"prefix":"10.3233","author":[{"given":"Mo","family":"Zhou","sequence":"first","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiming","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zelin","family":"Du","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiancheng","family":"Yi","sequence":"additional","affiliation":[{"name":"Spallation Neutron Source Science Center, Dongguan, 523803, Guangdong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianxi","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"},{"name":"Beijing Radiation Center, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiguo","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Beijing Key Laboratory of Applied Optics, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"},{"name":"Beijing Radiation Center, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yude","family":"Li","sequence":"additional","affiliation":[{"name":"College of Nuclear Science and Technology, Beijing Normal University, Beijing 100875, China"},{"name":"Beijing Key Laboratory of Applied Optics, Beijing 100875, China"},{"name":"Key Laboratory of Beam Technology, Ministry of Education, Beijing 100875, China"},{"name":"Beijing Radiation Center, Beijing 100875, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Proceedings of CECNet 2022"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA220577","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,12,21]],"date-time":"2022-12-21T08:03:44Z","timestamp":1671609824000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA220577"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12,13]]},"ISBN":["9781643683683","9781643683690"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia220577","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,12,13]]}}}
