Abstract

We describe our concept detection system submitted for the ImageCLEFmed Caption task, part of the ImageCLEF 2019 challenge. The advancements in imaging technologies has improved the ability of clinicians to detect, diagnose, and treat diseases. Radiologists routinely interpret medical images and summarise their findings in the form of radiology reports. The mapping of visual information present in medical images to the condensed textual description is a tedious, time-consuming, expensive, and error-prone task. The development of methods that can automatically detect the presence and location of medical concepts in medical images can improve the efficiency of radiologists, reduce the burden of manual interpretation, and also help in reducing diagnostic errors. We propose a Convolutional Neural Network based multi-label image classifier to predict relevant concepts present in medical images. The proposed method achieved an F1-score of 0.1435 on the held-out test set of the 2019 ImageCLEFmed Caption Task. We present our proposed system with data analysis, experimental results, comparison, and discussion.
