Microwave Head Imaging System for Detection of Blood Clots inside the Brain

Microwave head imaging can be a cost-effective alternative to MRI or CT scan for detection of any strong scattering object such as- a tumor or blood clot inside the brain. In this paper, a microwave head imaging system is proposed for detection and localization of a blood clot inside the brain by dividing the head imaging plane into four quarters and scanning over one quarter at a time. A miniaturized wideband antipodal Vivaldi antenna design is incorporated to scan the head using a monostatic approach. An image of the head is reconstructed by scanning each quarter of the head. Finally, the images obtained from four quarters are compared for detection and approximate localization of the blood clot inside the brain.
