Content-based medical image retrieval method and retrieval system

Abstract

A content-based medical image retrieval method and a retrieval system using the same include: obtaining m (2≤m≤n) number of unit images from a three-dimensional (3D) medical image including n (n≥2) number of unit images and extracting features per unit image from each of the m (2≤m≤n) number of unit images through a feature extraction unit, wherein the 3D medical image is voxel data including a plurality of slices and each of the plurality of slices is defined as a unit image; inputting features of each unit image extracted from the m (2≤m≤n) number of unit images to a recurrent neural network to generate an output value; and performing medical image retrieval using the output value through an input processing unit, wherein a plurality of 3D medical images to be compared with the output value include a 3D medical image having p (p≥2, p≠n) number of unit images.
