Human Lung Non-Invasive Anomaly Detection through UWB Microwave Imaging and Diagnosis of COVID-19: A Possible Application

This study shows a prototype for detecting lung effects using microwave imaging. Continuous monitoring of pulmonary fluid levels is one of the most successful approaches for detecting fluid in the lung;early Chest X-rays, computational tomography (CT)-scans, and magnetic resonance imaging (MRI) are the most commonly used instruments for fluid detection. Nonetheless, they lack sensitivity to ionizing radiation and are inaccessible to the general public. This research focuses on the development of a low-cost, portable, and noninvasive device for detecting Covid-19 or lung damage. The simulation of the system involved the antenna design, a 3D model of the human lung, the building of a COMSOL model, and image processing to estimate the lung damage percentage. The simulation consisted of three components. The primary element requires mode switching for four array antennas (transmit and receive). In the paper, microwave tomography was used. Using microwave near-field imaging, the second component of the simulation analyses the lung's bioheat and electromagnetic waves as well as examines the image creation under various conditions;many electromagnetic factors seen at the receiving device are investigated. The final phase of the simulation shows the affected area of the lung phantom and the extent of the damage. © 2023 IEEE.

Study of UWB Near Field Microwave Imaging System for the Diagnosis of Lungs Damage Due to Fluid Accumulations

Lung damages, which is the leading cause of cancer and Covid-19 related death worldwide, can be better treated, and patients' chances of survival increased with early detection and diagnosis. PET (positron emission tomography), cone beam CT, Low dose helical CT, are advanced lung imaging techniques that allow for early diagnosis of smaller pulmonary nodules than normal chest radiography, but with ionizing radiation effect and being costly. In the field of imaging technology, microwave imaging has long been researched in the field of breast and brain. This study presents a review, conducts a feasibility study, and validates the concept of imaging the lungs in a similar manner to the breast and brain. The analysis includes designing a 3D human lung model, microwaves' various elements and factors inspection through the human body using holographic near field imaging, and image processing to estimate the percentage of lung damage. The safety and ionization exposure were also taken into consideration during the overall experiment. The use of microwave energy in various lung diseases is examined, and the basis for fluid detection utilizing microwave water content accumulation is also addressed compared to normal tissues. © 2022 IEEE.
