Aimed at the lack of signal pretreatment in the artificial anal sphincter system, we find a way to solve it, that is, the multi-dimensional reconstruction of the intestinal one-dimensional pressure signal sequence by using phase space reconstruction, and the separation of the reconstructed signal by using the improved fast independent component analysis algorithm. We did some relevant experiments, further extracted the features of the isolated rectal signal, and used back propagation neural network to diagnose the rectal lesions. Experiments show that the method can pretreat the rectal signal, and further analyze the separated signal to diagnose of rectal function. The improved fast independent component analysis algorithm has few iterations, fast convergence, short run time, low requirements on initial weights and good diagnosis. This study lays a foundation for the diagnosis of rectal function by using artificial anal sphincters.<\/jats:p>","DOI":"10.1177\/0391398819852363","type":"journal-article","created":{"date-parts":[[2019,6,13]],"date-time":"2019-06-13T06:16:56Z","timestamp":1560406616000},"page":"636-644","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Research of improved fast independent component analysis algorithm in rectal diagnosis signal preprocessing"],"prefix":"10.1177","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2588-2188","authenticated-orcid":false,"given":"Peng","family":"Zan","sequence":"first","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai, People\u2019s Republic of China"},{"name":"Shanghai Key Laboratory of Power Station Automation Technology, Shanghai, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingjie","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meihan","family":"Chang","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering and Automation, Shanghai University, Shanghai, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,6,13]]},"reference":[{"key":"bibr1-0391398819852363","volume-title":"Key technologies research on artificial anal sphincter with sensor feedback powered by transcutaneous energy transmission","author":"Peng Z","year":"2009"},{"key":"bibr2-0391398819852363","volume-title":"Colonic pressure data analysis based on time frequency analysis and independent component analysis","author":"Chenjia C","year":"2009"},{"key":"bibr3-0391398819852363","doi-asserted-by":"publisher","DOI":"10.1007\/s10439-016-1572-z"},{"key":"bibr4-0391398819852363","doi-asserted-by":"publisher","DOI":"10.1111\/aor.12874"},{"key":"bibr5-0391398819852363","doi-asserted-by":"crossref","unstructured":"Zan P, Zhang C, Zhang S, et al.
