Advantages and limitations between traditional- and acoustic-lung imaging in assessing lung function.

	Traditional Lung Function Assessment (Chest X-ray, CT, MRI)	Acoustic Imaging Lung Assessment
Benefits	Typically outputs high image resolutions Planar lung imaging, two- and three-dimensional image assessment Established approach for diagnostic purposes Typically results have high sensitivity and specificity	Typically portable and accessible, hospital/equipment-to-patient approach Lower operation costs, reducing time in preparing patients for assessment Planar lung imaging, fast assessment time Reduced disease cross-contamination risk of transporting patients, particularly in a hospital setting Established approach for early analysis of lung function Frequent lung function assessment due to nonionizing approach
Limitations	Moderate accessibility, patient-to-equipment/hospital approach High operating cost, requiring patient preparation and planning or assessment Radiation factor Risk of cross-contamination of diseases in a hospital setting through patient transport to the equipment	Low image resolution Typically for assessment, unsuitable for diagnostic purposes Limited surface visualization Lower sensitivity compared to traditional lung function assessment
