Compared to other treatment modalities, RFA has a higher local tumor recurrence rate due to incomplete ablation. On the other hand, to ensure complete tumor removal, multiple ablations may be necessary, but this can lead to excessive thermal damage. Therefore, improving the precision of the ablation margin control is crucial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aims to investigate an algorithm-controlled ablation mode that can precisely control the tumor treatment margins. This mode uses temperature and impedance as feedback parameters to adaptively adjust the RF power output, ensuring both effective tumor ablation and enhanced safety.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study conducted finite element analyses and ex-vivo bovine liver experiments comparing traditional constant power ablation and the algorithm-controlled ablation mode. Simulations primarily analyzed the temperature changes and ablation area in biological tissue, assessing the effectiveness of the two ablation modes. In the ex-vivo bovine liver experiments, temperature and impedance were monitored in real-time to validate the feasibility of the algorithmic ablation mode.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The findings indicate that the algorithm-controlled ablation mode effectively controls the rise in tissue impedance, preventing carbonization and charring. For ablation diameters of 10\u2005mm and 20\u2005mm, it precisely maintained the boundary temperatures within the range of 50\u201360\u00b0C, ensuring effective damage at the ablation margins while avoiding excessive damage to normal tissue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study developed an adaptive radiofrequency ablation algorithm for treating liver cancer, using temperature and impedance as feedback parameters. Preliminary results from finite element analysis and ex-vivo bovine liver experiments suggest that for small tumors with diameters of 10\u2005mm and 20\u2005mm, this algorithm may provide more precise control of the ablation zone, improving efficiency and safety compared to traditional constant power ablation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09592989241304992","type":"journal-article","created":{"date-parts":[[2024,12,13]],"date-time":"2024-12-13T02:35:49Z","timestamp":1734057349000},"page":"133-147","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Algorithm-controlled RF power output for enhanced margin precision in liver cancer radiofrequency ablation"],"prefix":"10.1177","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-3590-7880","authenticated-orcid":false,"given":"Dandan","family":"Gu","sequence":"first","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Difang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haitao","family":"Yao","sequence":"additional","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danni","family":"Rui","sequence":"additional","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2794-766X","authenticated-orcid":false,"given":"Yu","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,12,12]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.5582\/bst.2022.01245"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i20.5987"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ueg2.12286"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.3109\/03091902.2012.754510"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2954"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/13645706.2021.1995436"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1088\/1361-6560\/ab36a1"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12880-019-0360-2"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1159\/000367733"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.3390\/cancers13163926"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0929-8266(01)00126-4"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-004-0253-9"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1115\/1.4038237"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2016.08.115"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1186\/1475-925X-10-34"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2011.2180722"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11517-016-1589-3"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1526-4637.2005.00076.x"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.3109\/02656736.2014.984000"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.1111\/jce.14709"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0245145"},{"key":"e_1_3_3_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/0005-2795(78)90558-5"},{"key":"e_1_3_3_24_2","first-page":"278","article-title":"Characteristics of heat transfer and determination of temperature gradient and viability threshold during radiofrequency fulguration of isolated perfused canine right ventricle","volume":"76","author":"De HJ","year":"1987","unstructured":"De HJ.
