A Text-Image Adapter Fusion Framework for 3D Pulmonary Vessel Segmentation
摘要
Accurate segmentation of 3D blood vessels has significant value in clinical diagnosis and surgical planning. However, challenges such as thin tubular structures, low contrast, complex branching patterns, and a scarcity of high-quality annotated data pose substantial difficulties for deep learning-based methods. With the emergence of pre-trained visual-language foundation models such as Contrastive Language-Image Pre-training (CLIP), research on general computer vision tasks has entered a new stage. However, in vessel segmentation tasks, these models still exhibit significant performance shortcomings. To fully leverage the cross-modal semantic capabilities of CLIP, we propose a novel fine-tuning framework called AdaBCA-CLIP, which uses pre-trained CLIP model as a powerful feature extractor for 3D CT scans. Building on this, we introduce a specially designed adapter module paired with a self-adaptive learning strategy to effectively fuse text and image modality embeddings. In addition, we design a Bi-directional Cross-Attention module to facilitate complementary information exchange between image and text features. The experiment was conducted on the public PARSE2022 dataset and our private PAV-Seg3D dataset. Experiments have shown that AdaBCA-CLIP outperforms other state-of-the-art methods in metrics such as Dice, Jaccard, and HD95.
