We propose a multi-objective\n\t\t\t\t\toptimization (MO) method for structured illuminations to balance the\n\t\t\t\t\treconstruction quality and radiation dose in a dynamic CXT system. The\n\t\t\t\t\tMO framework is established based on a dynamic sensing geometry with\n\t\t\t\t\tbinary coding masks. The Strength Pareto Evolutionary Algorithm 2 is\n\t\t\t\t\tused to solve the MO problem by jointly optimizing the coding masks,\n\t\t\t\t\tlocations of x-ray sources, and exposure moments. Computational\n\t\t\t\t\texperiments are implemented to assess the proposed MO method. They\n\t\t\t\t\tshow that the proposed strategy can obtain a set of Pareto optimal\n\t\t\t\t\tsolutions with different levels of radiation dose and better\n\t\t\t\t\treconstruction quality than the initial setting.<\/jats:p>","DOI":"10.1364\/ao.428871","type":"journal-article","created":{"date-parts":[[2021,6,22]],"date-time":"2021-06-22T13:00:09Z","timestamp":1624366809000},"page":"6177","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Multi-objective optimization for structured illumination in dynamic x-ray tomosynthesis"],"prefix":"10.1364","volume":"60","author":[{"given":"Xu","family":"Ma","sequence":"first","affiliation":[{"name":"Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0081-3947","authenticated-orcid":true,"given":"Hao","family":"Xu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos M.","family":"Restrepo","sequence":"additional","affiliation":[{"name":"University of Delaware"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gonzalo R.","family":"Arce","sequence":"additional","affiliation":[{"name":"University of Delaware"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2021,7,16]]},"reference":[{"key":"ao-60-21-6177-R1","doi-asserted-by":"publisher","first-page":"R65","DOI":"10.1088\/0031-9155\/48\/19\/R01","volume":"48","author":"Dobbins","year":"2003","journal-title":"Phys.
