Lung disorders or injury can result in changes in the production of lung sounds both spectrally and regionally. Localizing these lung sounds can provide information to the extent and location of the disorder. Difference in arrival times at a set of sensors and triangulation were previously proposed for acoustic imaging of the chest. We propose two algorithms for acoustic imaging using a set of ...

In order to evaluate the relationship between the concentration of welding fumes and cigarette smoke on the bronchopulmonary system function, a comparative study of spirometric measurements in 100 welders and 50 healthy volunteers was performed in an automobile manufacturing company. Two groups of workers were matched according to their age, height, smoking habit, years of service and soci...

(1) Background: Microwave ablation (MWA) has an efficient killing effect on primary and metastatic lung cancer. However, the treatment will be affected by air in lung, which makes it very difficult to accurately predict control area; (2) Methods: In this paper, vitro experiments combined with simulations are used study microwave area of inflated porcine lung. The experiment is divided into grou...
