| # 3DLAND: 3D Lesion Abdominal Anomaly Localization Dataset | |||||
| We introduce **3DLAND**, the first large-scale, **organ-aware** 3D lesion segmentation dataset for contrast-enhanced **abdominal CT scans**. | |||||
| This repository contains the code and dataset instructions for **3DLAND**, the first large-scale, organ-aware 3D lesion segmentation benchmark for abdominal CT scans, introduced at *ACM Multimedia 2025*. | |||||
| - 📦 **6,000+** CT volumes | |||||
| - 🧠 3D Lesions labeled across **7 abdominal organs**: liver, kidneys, spleen, pancreas, stomach, gallbladder | |||||
| - 🤖 Built using a **prompt-driven**, expert-verified segmentation pipeline | |||||
| - ⚙️ Designed for tasks such as anomaly detection, lesion retrieval, and multimedia-driven clinical AI | |||||
| ## 🌐 Overview | |||||
| - 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 | |||||
| ## 🧠 Pipeline | |||||
| 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 | |||||
