Abstract

We present a method for detecting and delineating pneumothorax from X-Ray medical images by using a threestep processing pipeline: a deep learning classification module, responsible for detecting the possible existence of a collapsed lung within an image, followed by a segmentation model applied on the positive samples (as detected by the classification module). The last module attempts to eliminate possible artefacts based on their size. We demonstrate how the pipeline employed significantly improves the results, by increasing the mean-Dice coefficient metric by 0.13, in comparison with the performance of a single segmentation module. In addition to this, we demonstrate that using together specific state-of-the-art techniques leads to improved results, without employing techniques such as dataset enrichment from external sources, semi-supervised learning or pretraining on much larger medical datasets.
