Design of microwave wideband antenna for brain tumor imaging applications

Head imaging technique plays a vital role in the detection of an affected brain, such as strokes cancerous tumours caused by trauma. Current systems require the patient to be transported to the imaging device which increases the time taken to apply treatments, which leads to the patient’s conditions to be worsen. The antenna is designed in 3-D dimension with a wideband and unidirectional properties. The lower microwave frequencies are used in the antenna to detect size, location and intensity of the tumour.Existing techniques such as MRI,X-ray,CT Scan which has more radiation which harm the tissues. The system utilizes combination of a software defined and solidstate switching network to collect the imaging data. It can capture the input signals, which is suitable for detecting realistic brain deficiency. This microwave imaging technique will not harm the tissues. The concept has been validated through experimental data collection in image generation, and is capable of capturing images in less than a minute. A simplified head phantom was developed gathering the data and proved that the system was capable of locating targets with dielectric properties similar to brain tumors and bleeds.
