Microwave imaging technique for lung tumour detection

In this work, experimental results from a study on the feasibility of detecting tumour tissue in the lung within the thorax is reported. The thorax phantom was realised using tissue simulating liquids with matching dielectric properties. The microwave images were reconstructed from the acquired backscattered signals using the delay-and-sum imaging algorithm. The described microwave imaging technique shows that it is possible to detect tumour in the lung during breathing activities of inhalation and exhalation.
