Abstract (en)
[origin: WO2023280708A1] One aspect of the invention relates to an automatic method for the segmentation of a thrombus and a lesion caused by the thrombus in a three-dimensional brain image, said method comprising the following steps: - supervised training of at least one primary recurrent artificial neural network in order to provide a lesion prediction from an image; - supervised training of at least one secondary recurrent artificial neural network in order to provide a thrombus prediction from an image; - using each trained primary recurrent artificial neural network on each image of a set of images obtained from the three-dimensional image, and merging the lesion predictions obtained in order to obtain a set of lesion segmentations: o if the set of lesion segmentations comprises at least one segmentation, selecting the widest segmentation as the lesion segmentation; - using each trained secondary recurrent artificial neural network on each image of a set of secondary images obtained from the three-dimensional image, and merging the thrombus predictions obtained in order to obtain a set of thrombus segmentations: o if the set of thrombus segmentations comprises at least one segmentation, selecting, as the thrombus segmentation, the segmentation corresponding to a proximity condition dependent on the lesion segmentation.
