MedGAN: Advanced Medical Image Generation

Overview

MedGAN is a comprehensive framework for generating high-quality synthetic medical images using state-of-the-art Generative Adversarial Networks (GANs). The project focuses on brain tumor MRI scans and includes implementations of multiple cutting-edge GAN architectures optimized for medical imaging applications.

Features

• Multiple GAN Implementations:

  • DCGAN (Deep Convolutional GAN)
  • ProGAN (Progressive Growing of GANs)
  • StyleGAN2 (Style-based Generator with improvements)
  • WGAN (Wasserstein GAN with gradient penalty)

• Web Application Interface:

  • Generate synthetic brain MRI scans
  • Detect tumor types from uploaded MRI images
  • Interactive and user-friendly interface

• Pre-trained Models:

  • Models for three tumor types: Glioma, Meningioma, and Pituitary
  • ViT-based tumor detection model (92% accuracy)

Architecture Performance Comparison

Getting Started

Prerequisites

• Python 3.9+
• PyTorch 1.9+
• Flask (for web application)
• CUDA-capable GPU (recommended)

Installation

1. Clone the repository:

git clone https://github.com/mozaloom/medgan.git
cd medgan

2. Install required packages:

pip install -r requirements.txt

3. Run the web application:

python app.py

4. Access the web interface at http://localhost:5000

Usage

Web Application

The MedGAN web application offers two primary functionalities:

1. Generate synthetic brain MRI scans:

   • Select tumor type (Glioma, Meningioma, Pituitary)
   • Choose GAN architecture
   • Generate high-quality synthetic MRI images

2. Detect tumor types:

   • Upload brain MRI scans
   • Receive AI-powered tumor classification
   • View detection confidence scores

Check the individual model implementation files for specific training parameters.
