• —No Data Leakage: Splits created before augmentation

Intended Use

Primary Use Cases

• —Medical research and educational purposes
• —Kidney disease classification from CT scans
• —Computer-aided diagnosis (CAD) system development
• —Medical imaging research

Limitations

• —Model trained on specific dataset distribution
• —Should not be used as sole diagnostic tool
• —Requires clinical validation before medical use
• —Performance may vary on images from different scanners or protocols

How to Use

Installation

pip install torch torchvision pillow

Inference Example

import torch
from PIL import Image
from torchvision import transforms

# Load model
model = torch.load('model.pth')
model.eval()

# Prepare image
transform = transforms.Compose([
    transforms.Resize((384, 384)),
    transforms.ToTensor(),
    transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])
])

# Predict
image = Image.open('kidney_ct.jpg').convert('RGB')
image_tensor = transform(image).unsqueeze(0)

with torch.no_grad():
    output = model(image_tensor)
    probs = torch.softmax(output, dim=1)
    pred = output.argmax(1).item()

classes = ['Cyst', 'Normal', 'Stone', 'Tumor']
print(f"Prediction: {classes[pred]} ({probs[0][pred].item()*100:.1f}% confidence)")

Dataset

Name: nazmul0087/ct-kidney-dataset-normal-cyst-tumor-and-stone

The model was trained on the CT Kidney Dataset containing 12,446 CT scan images across 4 classes. The dataset consists of coronal and axial cuts from PACS systems, verified by medical professionals.

Ethical Considerations

• —This model is for research and educational purposes only
• —Not FDA approved or clinically validated
• —Should not replace professional medical diagnosis
• —Requires human oversight and clinical validation
• —May have biases from training data distribution
