| Abstract: | Objective To study the performance of a new detection system for cerebral hemorrhage based on a new physical model of cerebral hemorrhage.Methods The phase shift spectroscopy of magnetic induction（PSSMI） method was used at three operation frequencies（f1,f2,f3）.Different cerebral hemorrhage levels were simulated with saline solution of 0 to 100 mL.Results The phase resolution was up to 0.005°,the gain was in an adjustable range of-10-35 dB in detection system.The results of experimental simulation showed that the phase shift was proportional to the volume,conductivity of solution and the operation frequency.Conclusion It is demonstrated that the developed cerebral hemorrhage detection system is feasible. |
