New Locus framework guides AI attention to relevant anatomy in medical images

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Locus, a new framework designed to improve medical image classification by guiding a model's attention to diagnostically relevant anatomical regions. This method leverages pretrained segmentation foundation models to extract anatomical shape priors, avoiding the need for manual annotation or dedicated segmentation model training. Locus introduces a regularization term that balances attention between anatomical and background regions, penalizing the classifier when background attention is excessive. The framework has demonstrated consistent performance gains and more anatomically grounded attention across eight diverse medical imaging datasets, including dermoscopy, X-ray, histopathology, and cardiac MRI. AI

IMPACT This research could lead to more accurate and interpretable AI models in medical diagnostics by ensuring focus on critical anatomical features.

    Learning To Focus: Anatomy-Guided Attention Regularization for Medical Image Classification

    Medical image classification models are ideally expected to identify diagnostically relevant regions while making predictions, yet standard classification losses rarely provide spatial supervision. Explicit supervision via anatomical shape information, such as segmentation masks …
