Diagnostic Reliability
The study significantly improves diagnostic reliability for COVID-19 detection. By combining a custom CNN for local features and a pre-trained MobileNetV2 for global context, the model achieves a superior accuracy of 97.46%. This robust performance is critical for clinical environments where accurate early detection can impact patient outcomes and resource allocation. The framework's ability to differentiate COVID-19 from normal cases with high precision reduces false positives and ensures more trustworthy diagnostic results.
Furthermore, the extensive dataset used for training, comprising 25,408 samples from nine public sources, contributes to the model's enhanced reliability and generalizability across diverse patient populations and imaging conditions. This broad data exposure mitigates biases often found in models trained on smaller, less diverse datasets, making the proposed solution more dependable in real-world clinical scenarios.
Computational Efficiency
A key strength of this framework is its focus on computational efficiency. The proposed lightweight parallel CNN model contains only 3.5 million parameters, significantly fewer than many state-of-the-art transformer models and even some larger CNNs. This low parameter count directly translates to reduced memory requirements and faster inference times (0.0059 seconds), making it highly suitable for deployment in resource-constrained healthcare settings, mobile diagnostic units, or integration with existing PACS systems without requiring substantial hardware upgrades.
This efficiency allows for rapid diagnostic turnaround, which is essential during public health crises when timely results are critical for patient management and epidemiological control. The careful design of the custom CNN and the strategic use of MobileNetV2 as a backbone demonstrate a commitment to practical utility alongside high performance, addressing a common challenge in deploying complex AI models in medical imaging.
Explainable AI (XAI)
To foster trust and clinical adoption, the framework incorporates Explainable AI (XAI) techniques, specifically Grad-CAM and LIME. These methods provide visual interpretations of the model's predictions by highlighting the specific regions in the CT scans that most influence its classification decisions. This transparency is crucial for clinicians, allowing them to verify that the model is focusing on medically pertinent features, such as ground-glass opacities (GGOs), rather than spurious correlations.
By aligning model predictions with expert radiological knowledge, XAI enhances the utility of the AI system beyond a 'black box' output. It enables better understanding, validation, and potential refinement of the model, which is vital in safety-critical applications like medical diagnosis. This feature is particularly valuable for training purposes and for building confidence among medical professionals in the AI's recommendations.
