Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological examination with MRI/CT scans which is costly and time consuming. Microwave Tomography (MWT) is proposed as a feasible, cost effective and portable system to diagnose the occurrence of hemorrhage based on tissue dielectric properties. The designed head phantom with hemorrhage is surrounded by eight dipole antennas radiating at 1GHz. Electromagnetic waves physics is used in finding the scattered electric field and the data is exported into MATLAB® for image reconstruction using Contrast Source Inversion (CSI) algorithm.
