ManuSpec Medical AI Pneumonia Detection (Computer Vision)
Description
Pneumonia is one of the leading causes of death globally, and its diagnosis from chest X-rays requires expert radiological interpretation.
This project showcases an end-to-end Computer Vision system to assist in this critical task, using transfer learning, a pre-trained EfficientNet model was fine-tuned on a public dataset of thousands of X-ray images.
The project involved building a custom data pipeline in PyTorch with data augmentation, writing a full training and evaluation program, and implementing Grad-CAM to ensure model explainability.
The result is a highly accurate and transparent deep learning model that can serve as a powerful decision-support tool in a clinical setting.
- Key Features:
- Exceptional Sensitivity (98% Recall): Excels at the most critical task by correctly identifying 98% of all actual pneumonia cases.
- High-Accuracy Diagnosis (90%): Achieves 90% overall accuracy on the unseen test set, demonstrating robust performance.
- Explainable AI (XAI) Heatmaps: Utilizes Grad-CAM to generate intuitive heatmaps, providing visual evidence of which lung regions the model focused on for its diagnosis.
- Rapid Triage Capability: Analyzes an X-ray in seconds, creating the potential to prioritize critical cases in a clinical workflow and reduce patient wait times from hours to minutes.
