GuideGen: A Text-Guided Framework for Paired Full-torso Anatomy and CT Volume Generation

AAAI 2026technical

The recently emerging conditional diffusion models seem promising for mitigating the labor and expenses in building large 3D medical imaging datasets. However, previous studies on 3D CT generation primarily focus on specific organs characterized by a local structure and fixed contrast and have yet t

Towards All-in-One Medical Image Re-Identification

CVPR 2025poster

Medical image re-identification (MedReID) is under-explored so far, despite its critical applications in personalized healthcare and privacy protection.In this paper, we introduce a thorough benchmark and a unified model for this problem.First, to handle various medical modalities, we propose a nove…

CAT: Coordinating Anatomical-Textual Prompts for Multi-Organ and Tumor Segmentation

NeurIPS 2024poster

Existing promptable segmentation methods in the medical imaging field primarily consider either textual or visual prompts to segment relevant objects, yet they often fall short when addressing anomalies in medical images, like tumors, which may vary greatly in shape, size, and appearance. Recognizin…

ZePT: Zero-Shot Pan-Tumor Segmentation via Query-Disentangling and Self-Prompting

CVPR 2024poster

The long-tailed distribution problem in medical image analysis reflects a high prevalence of common conditions and a low prevalence of rare ones which poses a significant challenge in developing a unified model capable of identifying rare or novel tumor categories not encountered during training. In…
