摘要：
The invention relates to a method for automatically processing at least one image slice of a given part of at least one lung of a patient suffering from a pathology that causes a bronchial infection by diffuse dilatation of the bronchial tubes of the lungs, the method comprising steps of segmenting (102) the at least one image slice of the given part of the lung, in order to produce a histogram characterising the pulmonary density of the given part of the lunch, by means of the voxels of the at least one image slice, each voxel being assocaited with a given pulmonary density； calculating (104) a threshold, from the histogram, corresponding to a threshold pulmonary density, based on at least one characteristic of the histogram, a first characteristic being the mode of the histogram； determining (106) from the at least one image slice of the given part of the lung, a pulmonary volume having a pulmonnar density higher or lower than the calculatedd threshold, corresponding to the sum of the voxels having a pulmonary density higher or lower than the calculated threshold； and calculating (110) an automatic score on the basis of the determined pulmonary volume, in order to monitor the evolution of the broncial infection of the patient.
