Higher Chest X-ray Resolution Improves Classification Performance

no code implementations9 Jun 2023 Alessandro Wollek, Sardi Hyska, Bastian Sabel, Michael Ingrisch, Tobias Lasser

Deep learning models for image classification are often trained at a resolution of 224 x 224 pixels for historical and efficiency reasons.

WindowNet: Learnable Windows for Chest X-ray Classification

no code implementations9 Jun 2023 Alessandro Wollek, Sardi Hyska, Bastian Sabel, Michael Ingrisch, Tobias Lasser

Finally, we propose and evaluate WindowNet, a model that learns optimal window settings, and show that it significantly improves performance compared to the baseline model without windowing.

Automated Labeling of German Chest X-Ray Radiology Reports using Deep Learning

no code implementations9 Jun 2023 Alessandro Wollek, Philip Haitzer, Thomas Sedlmeyr, Sardi Hyska, Johannes Rueckel, Bastian Sabel, Michael Ingrisch, Tobias Lasser

In this work, we explore the potential of weak supervision of a deep learning-based label prediction model, using a rule-based labeler.

German CheXpert Chest X-ray Radiology Report Labeler

no code implementations5 Jun 2023 Alessandro Wollek, Sardi Hyska, Thomas Sedlmeyr, Philip Haitzer, Johannes Rueckel, Bastian O. Sabel, Michael Ingrisch, Tobias Lasser

This study aimed to develop an algorithm to automatically extract annotations for chest X-ray classification models from German thoracic radiology reports.

Attention-based Saliency Maps Improve Interpretability of Pneumothorax Classification

1 code implementation3 Mar 2023 Alessandro Wollek, Robert Graf, Saša Čečatka, Nicola Fink, Theresa Willem, Bastian O. Sabel, Tobias Lasser

Conclusion: ViTs performed similarly to CNNs in CXR classification, and their attention-based saliency maps were more useful to radiologists and outperformed GradCAM.

A knee cannot have lung disease: out-of-distribution detection with in-distribution voting using the medical example of chest X-ray classification

1 code implementation1 Aug 2022 Alessandro Wollek, Theresa Willem, Michael Ingrisch, Bastian Sabel, Tobias Lasser

The proposed IDV approach trained on ID (chest X-ray 14) and OOD data (IRMA and ImageNet) achieved, on average, 0. 999 OOD AUC across the three data sets, surpassing all other OOD detection methods.
