| Conditional Positional Encoding (PEG) | Enables spatial adaptability using depthwise convolutional encoding. |
| ConvStem-Lite Integration | Combines CNN-based local feature learning with transformer-based global attention for subtle lesion detection. |
| Token Sparsity Regularization | Encourages focus on informative regions, aiding interpretability. |
| Class-Attention Pooling | Effectively decouples token-level representation learning from class aggregation. |
| Balanced Grad-CAM Visualization | Generates interpretable heatmaps for both TB and normal cases, offering transparency and diagnostic confidence. |
Clinical Interpretability & Trust
The model's ability to focus on clinically relevant areas in chest X-rays is crucial. Grad-CAM heatmaps generated by our framework highlight regions corresponding to opacities or nodules, directly aligning with radiologists' interpretations. This visual reinforcement builds significant trust in the AI's diagnostic suggestions, making it a powerful assistant in real-world clinical workflows. It means faster, more accurate diagnoses and ultimately better patient outcomes, especially in high-volume screening scenarios.
Challenge: Manual interpretation of chest X-rays is subjective and time-consuming, leading to inter-observer variability and potential delays in diagnosis, especially for subtle abnormalities.
Solution: Our enhanced ViT model provides clear visual explanations via Grad-CAM, highlighting disease-specific regions. This transparency allows radiologists to quickly validate AI suggestions.
Outcome: Improved diagnostic confidence and efficiency for radiologists, reducing interpretation time and variability. The model acts as a reliable AI assistant, leading to earlier detection and better patient management.
