  • METHOD FOR GENERATING A BIOMARKER, SYSTEM
    Publication number: 20220301158
    Abstract: A Method for generating a biomarker includes acquiring an image using an MRI system; processing the MRI image to generate a three-dimensional image of the lung; generating a first function corresponding to the distribution of the different signal intensity values; automatically calculating a filtering threshold of the first function from a second signal intensity value distribution function; segmenting a lung volume comprising: a main volume; a filtered volume of a volume of voxels quantified by the first function and filtered by at least the calculated filtering threshold, normalizing the values of the three-dimensional image of the lung volume; generating a biomarker indicating a normalized segmented volume ratio.

  • Method for geometrical characterisation of the airways of a lung by MRI
    Patent number: 11361429
    Abstract: An MRI method is disclosed for the geometrical characterisation of pulmonary airways on the basis of a first tridimensional image of at least one bronchus of a bronchial tree and includes: acquiring a first MRI image, an MRI sequence being synchronised with a respiratory frequency; filtering the first image; segmenting a portion of the filtered image including the contours of the bronchial tree and its inner volumetric portion; estimating at least one plane of cut of a bronchus; generating at least one image slice of a bronchus; estimating, for each image slice, an area contained within the bronchial wall and/or a bronchial wall thickness.
