Interactive-MEN-RT

Domain-Specialized Interactive Segmentation for Meningioma Radiotherapy Planning

Status: Research prototype — Not for clinical use.

Overview

Interactive 3D meningioma segmentation framework built on nnU-Net v2 and nnInteractive.

• Performance: 77.6% Dice, 64.8% IoU (BraTS 2025 Meningioma RT)
• Interaction Modes: Point, scribble, box, lasso
• Input: T1c MRI (contrast-enhanced)

Quick Start

from huggingface_hub import snapshot_download
import os

# Download checkpoint
root = snapshot_download(
    "hanjang/Interactive-MEN-RT",
    allow_patterns=["nnUNetInteractionTrainer__nnUNetPlans__3d_fullres_scratch/**"]
)
CKPT = os.path.join(root, "nnUNetInteractionTrainer__nnUNetPlans__3d_fullres_scratch")

# Load and run inference
from Interactive_MEN_RT_predictor import InteractiveMENRTPredictor
import torch, numpy as np

predictor = InteractiveMENRTPredictor(
    device=torch.device("cuda" if torch.cuda.is_available() else "cpu")
)
predictor.initialize_from_trained_model_folder(
    model_training_output_dir=CKPT,
    use_fold=0,
    checkpoint_name="checkpoint_best.pth"
)

# Run on your volume (shape: 1, H, W, D)
predictor.reset_interactions()
predictor.set_image(volume)
predictor.set_target_buffer(np.zeros_like(volume[0], np.float32))
predictor._finish_preprocessing_and_initialize_interactions()
predictor._predict_without_interaction()
prediction = (predictor.target_buffer > 0.5).astype(np.uint8)
