UWB microwave imaging of the lungs: A review

Microwave imaging had been around for some time in the research field of imaging technologies. Most researchers have focused on breast imaging and a few others on brain imaging. This article presents a review, a part feasibility study and proves of concept into the possibility of imaging the lungs in similar manner as the breast and brain. We present reviews of usage of microwave energy in various lung-heart related diseases, heart and breathe detector and lung tumour detection. The basis for tumour detection using microwave, various tumour and normal tissues compared were also reviewed. We aim to motivate researchers towards imaging the lungs using UWB microwave imaging methods.
