Imaging of Pulmonary Edema with Microwaves – Preliminary Investigation

An immediate medical care requiring threat called pulmonary edema is considered in this study. In order to detect water a in human lungs, a microwave inversion scheme based Born iterative method (BIM) is implemented. To that end, a realistic human torso phantom is used and dielectric parameters of tissues and organs are estimated via Cole-Cole model at desired frequency. Then, scattered electric field is calculated synthetically by method of moments. Simulations are performed at 350 MHz and the region between phantom and antennas are surrounded by a dielectric material with permittivity of 30. In the numerical results section, performance assessment of BIM is tested for two cases. The numerical results suggest that the BIM is capable of detecting water accumulation in human lungs.
