+# Description
+A pre-trained model for volumetric (3D) multi-organ segmentation from CT image.
+
+# Model Overview
+A pre-trained Swin UNETR [1,2] for volumetric (3D) multi-organ segmentation using CT images from Beyond the Cranial Vault (BTCV) Segmentation Challenge dataset [3].
+## Data
+The training data is from the [BTCV dataset](https://www.synapse.org/#!Synapse:syn3193805/wiki/89480/) (Please regist in `Synapse` and download the `Abdomen/RawData.zip`).
+The dataset format needs to be redefined using the following commands:
+
+```
+unzip RawData.zip
+mv RawData/Training/img/ RawData/imagesTr
+mv RawData/Training/label/ RawData/labelsTr
+mv RawData/Testing/img/ RawData/imagesTs
+```
+
+- Target: Multi-organs
+- Task: Segmentation
+- Modality: CT
+- Size: 30 3D volumes (24 Training + 6 Testing)
+
+## Training configuration
+The training was performed with at least 32GB-memory GPUs.
+
+Actual Model Input: 96 x 96 x 96
+
+## Input and output formats
+Input: 1 channel CT image
+
+Output: 14 channels: 0:Background, 1:Spleen, 2:Right Kidney, 3:Left Kideny, 4:Gallbladder, 5:Esophagus, 6:Liver, 7:Stomach, 8:Aorta, 9:IVC, 10:Portal and Splenic Veins, 11:Pancreas, 12:Right adrenal gland, 13:Left adrenal gland
+
+## Performance
+A graph showing the validation mean Dice for 5000 epochs.
+
+![](./val_dice.png) <br>
+
+This model achieves the following Dice score on the validation data (our own split from the training dataset):
+
+Mean Dice = 0.8283
+
+Note that mean dice is computed in the original spacing of the input data.
+## commands example
+Execute training:
+
+```
+python -m monai.bundle run training --meta_file configs/metadata.json --config_file configs/train.json --logging_file configs/logging.conf
+```
+
+Override the `train` config to execute multi-GPU training:
+
+```
+torchrun --standalone --nnodes=1 --nproc_per_node=2 -m monai.bundle run training --meta_file configs/metadata.json --config_file "['configs/train.json','configs/multi_gpu_train.json']" --logging_file configs/logging.conf
+```
+
+Override the `train` config to execute evaluation with the trained model:
+
+```
+python -m monai.bundle run evaluating --meta_file configs/metadata.json --config_file "['configs/train.json','configs/evaluate.json']" --logging_file configs/logging.conf
+```
+
+Execute inference:
+
+```
+python -m monai.bundle run evaluating --meta_file configs/metadata.json --config_file configs/inference.json --logging_file configs/logging.conf
+```
+
+Export checkpoint to TorchScript file:
+
+TorchScript conversion is currently not supported.

+# Description
+A pre-trained model for volumetric (3D) multi-organ segmentation from CT image.
+
+# Model Overview
+A pre-trained Swin UNETR [1,2] for volumetric (3D) multi-organ segmentation using CT images from Beyond the Cranial Vault (BTCV) Segmentation Challenge dataset [3].
+## Data
+The training data is from the [BTCV dataset](https://www.synapse.org/#!Synapse:syn3193805/wiki/89480/) (Please regist in `Synapse` and download the `Abdomen/RawData.zip`).
+The dataset format needs to be redefined using the following commands:
+
+```
+unzip RawData.zip
+mv RawData/Training/img/ RawData/imagesTr
+mv RawData/Training/label/ RawData/labelsTr
+mv RawData/Testing/img/ RawData/imagesTs
+```
+
+- Target: Multi-organs
+- Task: Segmentation
+- Modality: CT
+- Size: 30 3D volumes (24 Training + 6 Testing)
+
+## Training configuration
+The training was performed with at least 32GB-memory GPUs.
+
+Actual Model Input: 96 x 96 x 96
+
+## Input and output formats
+Input: 1 channel CT image
+
+Output: 14 channels: 0:Background, 1:Spleen, 2:Right Kidney, 3:Left Kideny, 4:Gallbladder, 5:Esophagus, 6:Liver, 7:Stomach, 8:Aorta, 9:IVC, 10:Portal and Splenic Veins, 11:Pancreas, 12:Right adrenal gland, 13:Left adrenal gland
+
+## Performance
+A graph showing the validation mean Dice for 5000 epochs.
+
+![](./val_dice.png) <br>
+
+This model achieves the following Dice score on the validation data (our own split from the training dataset):
+
+Mean Dice = 0.8283
+
+Note that mean dice is computed in the original spacing of the input data.
+## commands example
+Execute training:
+
+```
+python -m monai.bundle run training --meta_file configs/metadata.json --config_file configs/train.json --logging_file configs/logging.conf
+```
+
+Override the `train` config to execute multi-GPU training:
+
+```
+torchrun --standalone --nnodes=1 --nproc_per_node=2 -m monai.bundle run training --meta_file configs/metadata.json --config_file "['configs/train.json','configs/multi_gpu_train.json']" --logging_file configs/logging.conf
+```
+
+Override the `train` config to execute evaluation with the trained model:
+
+```
+python -m monai.bundle run evaluating --meta_file configs/metadata.json --config_file "['configs/train.json','configs/evaluate.json']" --logging_file configs/logging.conf
+```
+
+Execute inference:
+
+```
+python -m monai.bundle run evaluating --meta_file configs/metadata.json --config_file configs/inference.json --logging_file configs/logging.conf
+```
+
+Export checkpoint to TorchScript file:
+
+TorchScript conversion is currently not supported.
