Brain stroke, referred to as a local neurological deficit suddenly caused by abnormal blood flow to brain tissue, is the third leading cause of death after heart disease and cancer. Additionally, because of its very short golden hour, initial treatment and access to diagnostic devices are critical. The main equipment for diagnosing brain stroke are CT and MRI, but it is difficult to carry out continuous tests and the equipment are not portable. CT is detrimental to patients because it uses ionizing radiation, leading to the demand for new devices. Microwave-based imaging technology is emerging as a medical imaging tool to replace CT, based on the mapping of the electromagnetic scattering resulting from the difference in dielectric constant between tissues. Microwave imaging has the advantages of viability, low cost, portability, and radioactivity throughout a living tissue. Hence, it is an excellent technique for diagnosing blood flow abnormalities in the brain and a good imaging tool for managing brain stroke. In this study, tomography imaging has been applied to head imaging to develop portable and relatively inexpensive imaging technology. Further, a method for generating a 3-D image using the time delay of the reflected wave from the target has been proposed. With the application of the holography technique to the microwave method, the microwave imaging-based stroke diagnosis will continue to evolve, improving the quality of life.
