AURORA

Deep learning models for brain cancer metastasis segmentation based on the manuscripts:

• Identifying core MRI sequences for reliable automatic brain metastasis segmentation
• Development and external validation of an MRI-based neural network for brain metastasis segmentation in the AURORA multicenter study

Installation

With a Python 3.8+ environment, you can install brainles_aurora directly from pypi.org:

pip install brainles-aurora

Recommended Environment

• CUDA 11.4+ (https://developer.nvidia.com/cuda-toolkit)
• Python 3.8+
• GPU with CUDA support and at least 6GB of VRAM

Usage

BrainLes features Jupyter Notebook tutorials with usage instructions.

A minimal example could look like this:

    from brainles_aurora.inferer import AuroraInferer, AuroraInfererConfig

    config = AuroraInfererConfig(
        tta=False, cuda_devices="4"
    )  # disable tta for faster inference in this showcase
    inferer = AuroraInferer(config=config)

    inferer.infer(
        t1="t1.nii.gz",
        t1c="t1c.nii.gz",
        t2="t2.nii.gz",
        fla="fla.nii.gz",
        segmentation_file="segmentation.nii.gz",
        whole_tumor_unbinarized_floats_file="whole_network.nii.gz",
        metastasis_unbinarized_floats_file="metastasis_network.nii.gz",
        log_file="aurora.log",
    )
