Study of PSSMI for cerebral hemorrhage detection: An experimental simulation

Based on PSSMI we developed a new cerebral hemorrhage model and a new system for cerebral hemorrhage detection. This study evaluated experimentally the performance of our system through the simulation of phase shift measurements. Some phase shifts were measured at three operation frequencies. The phase resolution was up to 0.005° and the gain was −10∼35dB in the detection system. Different cerebral hemorrhage levels were simulated from 0 to 100 ml by volumes of saline solutions. The results of the experimental simulation show the phase shift is proportional to the volume, conductivity of the solution and the operation frequency. The experimental study provides obvious evidence that the PSSMI method has the potential to become a simple method for cerebral hemorrhage detection.
