Chest X-Ray Classifier

Quibim
Quibim’s Chest X-ray Classifier aims to help radiologists deal with the large volumes of chest radiographs by prioritizing potentially pathological cases. This AI-fueled app is able to automatically identify PA/AP acquisitions and estimate the presence probability of 15 different findings in chest radiographs. Once these 15 probabilities are calculated, the classifier combines them to quantify the final abnormal probability of an image. The suite provides heatmaps that are displayed over the analyzed radiographs and that show the level of influence of each region of an image in the final abnormality score. By segmenting both lungs, the tool extracts textural features to foster posterior radiomic studies.
