A pre-trained model for volumetric (3D) segmentation/annotation of the lung from CT images.
The model is trained using a 3D anisotropic hybrid network .
The training was performed with the following:
This model was trained on a global dataset with a large experimental cohort collected from across the globe. The CT volumes of 120 independent subjects are provided by NIH with experts’ lung region annotations.
Dice score is used for evaluating the performance of the model. On the test set, the trained model achieved score of 0.9414 for lung.
Training loss over 2000 epochs.
Validation mean dice score over 2000 epochs.
The model was validated with NVIDIA hardware and software. For hardware, the model can run on any NVIDIA GPU with memory greater than 16 GB. For software, this model is usable only as part of Transfer Learning & Annotation Tools in Clara Train SDK container. Find out more about Clara Train at the Clara Train Collections on NGC.
Full instructions for the training and validation workflow can be found in our documentation.
