Method for diagnosis of functional lung illnesses

摘要

In a method for diagnosing functional lung illnesses, image exposures of the lungs are obtained at various phase points in time of the respiration of a subject, such as at maximum inhalation and maximum expiration, and the image exposures are segmented and at least two of the image exposures are compared on a segment-by-segment basis to identify a change in tissue density between the compared segments, as an indicator of lung functioning.
