METHOD FOR THE GEOMETRIC CHARACTERIZATION OF AERIAL PATHWAYS OF A LUNG BY MRI

摘要

A method of geometric characterization from a three-dimensional image of the airways by MRI for the geometric characterization of at least one bronchus of a bronchial tree, said method comprising: an acquisition (ACQ_IMG) of a first MRI image (IM1 ), an MRI sequence being synchronized to a breathing frequency; ▪ a filtering (F) of the first image (IM1); ▪ a segmentation (SEG) of a portion of the filtered image (IM2) comprising the contours of the bronchial tree (1) and its internal volumetric portion; ▪ an estimate (EST PC) of at least one cutting plane (pk) of a bronchus (bp); ▪ A generation of at least one cut image (IMG CP) of a bronchus (bp); ▪ An estimate for each cut image (41, IM5pk): ○ of an area (52) included within the bronchial wall and / or; ○ a bronchial wall thickness (51).
