Wideband microwave head imaging system to detect subdural hematoma brain injury

An antenna is one of the essential components for all wireless communication. In medical diagnosis and treatment as an academic discipline, Biomedical engineering holds a conspicuous place. For transmitting and receiving power in the human body antenna plays an implanted role. In microwave head imaging system, we use an antenna array to emit a small amount of electromagnetic (EM) energy towards the head; the dispersed EM signals are processed to image the human head inside. Based on the received electrical properties of regular and irregular tissues of the human head the image is reconstructed. In microwave head imaging, backscattered signals are captured using an antenna, the target is located by digital signal processing, for data collection and image output image computation and software engineering is used. By severe head injury a collection of blood outside the brain may occur and is called subdural hematoma, which can be life-threatening. Subdural hematoma is either acute or chronic. An acute subdural hematoma is caused by a severe head injury. A chronic subdural hematoma is caused by a less head injury. This work presents a VHF/UHF dipole antenna for broadband wireless communication applications. A dipole antenna was designed, to work in the range of frequency (20 MHz – 3 GHz). A genetic algorithm (GA) optimizer will be used to determine the location of load circuits alongside an antenna arm. To configure antenna the bandwidth of antenna operation is maximized by using such an optimizer. The configuration of antenna measurements are characterized by a low voltage standing wave ratio (VSWR) and high gain. Other measurement characteristics can also be evaluated to ensure the ideal antenna operation beyond VSWR and gain.
