Determining data representing a change between sets of medical imaging data

Abstract

A computer implemented framework for determining data representing a change between first medical imaging data and second medical imaging data is disclosed. Imaging data representative of a difference between the first medical imaging data and the second medical imaging data is obtained. The imaging data is input into a trained image processing machine learning model to generate an image feature vector. A plurality of text feature vectors is obtained, each text feature vector being representative of natural language text describing a respective change in medical imaging data. For each of the plurality of text feature vectors, a similarity measure indicating a degree of similarity to the image feature vector determined. A text feature vector is selected. The data representing the change between the first medical imaging data and the second medical imaging data is determined based on the selected text feature vector.
