## π Overview |
|
|
|
</div> |
|
|
|
|
|
|
|
- 6,000+ contrast-enhanced CT studies |
|
|
|
- 3D lesion masks aligned with 7 abdominal organs |
|
|
|
- Prompt-based annotation and propagation pipeline |
|
|
|
- Applications: anomaly detection, lesion retrieval, organ-aware analysis |
|
|
|
We introduce **3DLAND**, the first large-scale, **organ-aware** 3D lesion segmentation dataset for contrast-enhanced **abdominal CT scans**. |
|
|
|
|
|
|
|
## π§ Pipeline |
|
|
|
- π¦ **6,000+** CT volumes |
|
|
|
- π§ 3D Lesions labeled across **7 abdominal organs**: liver, kidneys, spleen, pancreas, stomach, gallbladder |
|
|
|
- π€ Built using a **prompt-driven**, expert-verified segmentation pipeline |
|
|
|
- βοΈ Designed for tasks such as anomaly detection, lesion retrieval, and multimedia-driven clinical AI |
|
|
|
|
|
|
|
The lesion segmentation pipeline includes: |
|
|
|
1. Organ segmentation via MONAI |
|
|
|
2. Lesion-to-organ assignment |
|
|
|
3. 2D mask generation using SAM prompts |
|
|
|
4. 3D mask propagation using MedSAM2 |
|
|
|
This level of structured annotation would traditionally take **25+ years** of expert effort β 3DLAND accomplishes it in weeks using automated reasoning and deep learning. |
|
