Title:

AUTOMATIC SEGMENTATION PROCESS OF A 3D MEDICAL IMAGE BY ONE OR SEVERAL NEURAL NETWORKS THROUGH STRUCTURED CONVOLUTION ACCORDING TO THE ANATOMIC GEOMETRY OF THE 3D MEDICAL IMAGE

Document Type and Number:

WIPO Patent Application WO/2019/138001

Kind Code:

A1

Abstract:

This invention concerns an automatic segmentation method of a medical image making use of a knowledge database containing information about the anatomical and pathological structures or instruments, that can be seen in a 3D medical image of a x b x n dimension, i.e. composed of n different 2D images each of a x b dimension. Said method being characterised in that it mainly comprises three process steps, namely: a first step consisting in extracting from said medical image nine sub-images (1 to 9) of a/2 x b/2 x n dimensions, i.e. nine partially overlapping a/2 x b/2 sub-images from each 2D image; a second step consisting in nine convolutional neural networks (CNNs) analysing and segmenting each one of these nine sub-images (1 to 9) of each 2D image; a third step consisting in combining the results of the nine analyses and segmentations of the n different 2D images, and therefore of the nine segmented sub-images with a/2 x b/2 x n dimensions, into a single image with a x b x n dimension, corresponding to a single segmentation of the initial medical image.
