NiftyNet is a TensorFlow-based open-source convolutional neural networks (CNN) platform for research in medical image analysis and image-guided therapy. NiftyNet's modular structure is designed for sharing networks and pre-trained models. Using this modular structure you can:

• Get started with established pre-trained networks using built-in tools
• Adapt existing networks to your imaging data
• Quickly build new solutions to your own image analysis problems

NiftyNet is a consortium of research organisations (BMEIS -- School of Biomedical Engineering and Imaging Sciences, King's College London; WEISS -- Wellcome EPSRC Centre for Interventional and Surgical Sciences, UCL; CMIC -- Centre for Medical Image Computing, UCL; HIG -- High-dimensional Imaging Group, UCL), where BMEIS acts as the consortium lead.

• Easy-to-customise interfaces of network components
• Sharing networks and pretrained models
• Support for 2-D, 2.5-D, 3-D, 4-D inputs*
• Efficient training with multiple-GPU support
• Implementation of recent networks (HighRes3DNet, 3D U-net, V-net, DeepMedic)
• Comprehensive evaluation metrics for medical image segmentation

^{NiftyNet is not intended for clinical use.}

^{NiftyNet release notes are available here.}

^{*2.5-D: volumetric images processed as a stack of 2D slices; 4-D: co-registered multi-modal 3D volumes}

1. Please install the appropriate TensorFlow package*:
   • pip install tensorflow-gpu>=1.13.2 for TensorFlow with GPU support
   • pip install tensorflow>=1.13.2 for CPU-only TensorFlow
2. pip install niftynet

^{All other NiftyNet dependencies are installed automatically as part of the pip installation process.}

To install from the source repository, please checkout the instructions.

The API reference and how-to guides are available on Read the Docs.
