A pre-trained model for volumetric (3D) segmentation of the spleen from CT image.

Model Overview

This model is trained using the runner-up [1] awarded pipeline of the "Medical Segmentation Decathlon Challenge 2018" using the UNet architecture [2] with 32 training images and 9 validation images.


The training dataset is Task09_Spleen.tar from http://medicaldecathlon.com/.

Training configuration

The training was performed with at least 12GB-memory GPUs.

Actual Model Input: 96 x 96 x 96

Input and output formats

Input: 1 channel CT image

Output: 2 channels: Label 1: spleen; Label 0: everything else


This model achieves the following Dice score on the validation data (our own split from the training dataset):

Mean Dice = 0.96

commands example

Execute inference:

python -m monai.bundle run evaluator --meta_file configs/metadata.json --config_file configs/inference.json --logging_file configs/logging.conf

Verify the metadata format:

python -m monai.bundle verify_metadata --meta_file configs/metadata.json --filepath eval/schema.json

Verify the data shape of network:

python -m monai.bundle verify_net_in_out network_def --meta_file configs/metadata.json --config_file configs/inference.json

Export checkpoint to TorchScript file:

python -m monai.bundle export network_def --filepath models/model.ts --ckpt_file models/model.pt --meta_file configs/metadata.json --config_file configs/inference.json


This is an example, not to be used for diagnostic purposes.
