摘　　要：目的:模拟脑脊液分布变化建立物理模型并进行EIT实验分析。方法:选取不同琼脂块以模拟血液和脑脊液,分别仿照脑出血后将颅顶脑脊液排开和未排开2种模型进行成像实验,测量脑脊液分布对脑部出血成像的影响。结果:由于颅内血肿出现,改变了血肿周围脑脊液分布情况,影响了头部EIT结果。结论:当颅内出现血肿时,如果脑脊液受血肿挤压而重新分布,会对EIT结果有一定影响。Objective To construct the physical model simulating cerebrospinal fluid distribution changes and perform EIT experimental analysis.Methods Different agar blocks were used to simulate blood and cerebrospinal fluid.The influences of cerebrospinal fluid distribution on cerebral hemorrhage imaging were studied by the imaging experiments with the epicranial cerebrospinal fluid exhausted or un-exhausted after cerebral hemorrhage.Results The intracranial hematoma changed the distribution of the surrounding cerebrospinal fluid,and the head EIT imaging was also influenced.Conclusion The intracranial hematoma may make the cerebrospinal fluid re-distributed,and then pose its influence on EIT imaging.
