Therefore, timely detection and treatment of abdominal hemorrhage is crucial for the health and safety of patients. Magnetic induction tomography is a non-invasive, nonradioactive, and non-contact electromagnetic imaging technology with potential application value for disease screening and continuous monitoring. In this paper, a simulation model of electrical impedance distribution close to the real human abdominal tissue was constructed, and based on this model, the magnetic induction tomography simulation method of internal bleeding was studied by the finite element numerical method, and the comparison was verified by phantom experiments. The eddy current density distribution inside the abdominal tissue and the magnetic induction phase data at the tissue boundary are solved, and sensitivity analysis of phase differences caused by changes in the radius and position of bleeding volume was conducted, and three sensitivity indicators were proposed. Both the simulation and phantom experiment show that when there are six types of tissues with different conductivity in the abdomen, the radius of bleeding increases from 10 to 30\u00a0mm, and the radius phase difference sensitivity index Ar increases approximately linearly monotonically. Its radius transformation sensitivity Kr is 3.0961 \u00d7 10\u22125\u00b0\/cm. When the position of the bleeding volume changes, the sensitivity index Ax of the x-axis displacement phase difference shows a quasilinear monotonic decrease, and the x-axis displacement sensitivity Kx is \u22126.3744 \u00d7 10\u22126\u00b0\/cm. The y-axis displacement phase difference sensitivity Ay index shows a quasilinear relationship and monotonically increases, with a y-axis displacement sensitivity Ky of 5.2870 \u00d7 10\u22124\u00b0\/cm. The results indicate that the phase difference sensitivity before and after the occurrence of bleeding can be used as a quantitative monitoring indicator to monitor the occurrence and trend of intra-abdominal hemorrhage, laying the foundation for the preliminary screening and continuous monitoring of abdominal hemorrhage diseases using magnetic induction imaging.<\/jats:p>","DOI":"10.1063\/5.0214709","type":"journal-article","created":{"date-parts":[[2024,10,1]],"date-time":"2024-10-01T12:53:42Z","timestamp":1727787222000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Simulation study of abdominal hemorrhage based on magnetic induction tomography"],"prefix":"10.1063","volume":"95","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8267-5970","authenticated-orcid":false,"given":"Ruijuan","family":"Chen","sequence":"first","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0881-0942","authenticated-orcid":false,"given":"Yalin","family":"Du","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8148-702X","authenticated-orcid":false,"given":"Xinlei","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9910-2995","authenticated-orcid":false,"given":"Yuanxin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiquan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongsheng","family":"Sun","sequence":"additional","affiliation":[{"name":"Tianjin Huanhu Hospital 2 , Tianjin 300350,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhai","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Tiangong University 1 , Tianjin 300387,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2024,10,1]]},"reference":[{"key":"2024102112412486600_c1","doi-asserted-by":"publisher","first-page":"475","DOI":"10.1007\/s00261-021-03336-w","article-title":"CT of acute abdominopelvic hemorrhage: Protocols, pearls, and pitfalls","volume":"47","year":"2022","journal-title":"Abdom.
