TraumaNet DINOv3 ViT-Large Backbone

Overview

This repository hosts the TraumaNet DINOv3 ViT-Large backbone checkpoint used for downstream multi-task abdominal trauma detection on contrast-enhanced CT.

The checkpoint stored here is the pretrained backbone initialization used before downstream TraumaNet fine-tuning.

Intended Use

This checkpoint is intended to be used as the dinov3_pretrained initialization file in the TraumaNet downstream pipeline.

It is not a standalone end-to-end prediction package. To reproduce the downstream task, users should combine this checkpoint with the TraumaNet source code repository.

Expected Downstream Setting

The downstream TraumaNet pipeline uses:

contrast-enhanced abdominal CT
HU soft-tissue windowing
- window center = 40
- window width = 350
depth standardization to 240
2.5D grouping with 3 adjacent slices per group
DINOv3 ViT-Large backbone loading from this checkpoint

Limitations

This repository provides the backbone checkpoint only.
It does not provide the trauma dataset.
It does not provide train / validation / test labels.
It does not provide external evaluation data.
It does not provide a standalone inference API.
