| ## 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. | |||
