🧠 ArcLight — Early Detection of Neurological Disorders

Inspiration

Neurological disorders such as Alzheimer's Disease, Parkinson's Disease, Brain Tumors, Epilepsy, Multiple Sclerosis, and Stroke affect millions of people worldwide. Unfortunately, many of these conditions are diagnosed only after symptoms become severe, reducing the effectiveness of treatment.

We wanted to explore how Artificial Intelligence and Deep Learning could assist healthcare professionals by providing a fast, reliable, and accessible tool for analyzing MRI brain scans. Our vision was to create an intelligent assistant that supports early diagnosis, helping clinicians make faster and more informed decisions while improving patient outcomes.

What it does

ArcLight is an AI-powered medical imaging platform that detects neurological disorders from MRI brain scans using deep learning.

The platform enables users to:

🧠 Upload MRI brain scans
⚙️ Automatically preprocess medical images
🤖 Run AI-powered disease prediction
📊 Display prediction confidence scores
📈 Visualize diagnostic results
🌐 Access everything through an intuitive Streamlit web application

How we built it

The project combines Artificial Intelligence, Computer Vision, Medical Imaging, and Full-Stack Development into a unified healthcare solution.
