THORACIC DIAGNOSIS ASSISTANCE SYSTEM AND PROGRAM

摘要

The invention is able to provide physicians with information that facilitates understanding of the clinical features of lung field ventilation and is effective for diagnosis. In particular, diagnostic information is provided with which appropriate diagnoses can be made even by physicians with little practical experience in using stethoscopes. With the diagnostic console (3) of this thoracic diagnosis assistance system (100), the control unit (31) extracts lung field regions from each of the multiple image frames obtained by imaging the movements of the chest, divides the extracted lung field regions into a plurality of sub-regions, and correlates the various sub-regions between the multiple image frames. Thereafter, the multiple image frames corresponding to each sub-region are analyzed, characteristic inspiratory values and characteristic expiratory values are calculated for each sub-region, ratios of the calculated characteristic inspiratory values to characteristic expiratory values are calculated and histograms of the ratios thus calculated are generated. The generated histograms are displayed on the display unit (34).
