Quantum Autoencoder Shows Promise for Brain MRI Anomaly Detection

Researchers have developed a quantum autoencoder (QAE) for anomaly detection in brain MRI scans, utilizing angle encoding to map image patches into quantum states. This method trains a variational encoder-decoder to compress information, with anomalies identified by their resistance to compression. The QAE achieved a slice-level ROC-AUC of approximately 0.95 and a patch-level ROC-AUC of approximately 0.813, outperforming classical autoencoder and PCA baselines. The study highlights the potential of QAEs for interpretable and controllable anomaly detection in medical imaging. AI
