Intravascular ultrasound (IVUS) imaging provides two-dimensional (2-D) real-time luminal and transmural cross-sectional images of intravascular vessels with detailed pathological information. It has offered significant advantages in terms of diagnosis and guidance and has been increasingly introduced from coronary interventions into more generalized endovascular surgery. However, IVUS itself does not provide spatial pose information for its generated images, making it difficult to construct a 3-D intravascular visualization. To address this limitation, IVUS imaging-driven 3-D intravascular reconstruction techniques have been developed. These techniques enable accurate diagnosis and quantitative measurements of intravascular diseases to facilitate optimal treatment determination. Such reconstruction extends the IVUS imaging modality from pure diagnostic assistance to intraoperative navigation and guidance and supports both therapeutic options and interventional operations. This paper presents a comprehensive survey of technological advances and recent progress on IVUS imaging-based 3-D intravascular reconstruction and its state-of-the-art applications. Limitations of existing technologies and prospects of new technologies are also discussed.
血管内超声（IVUS）成像提供了血管腔内的二维（2-D）实时内腔和贯穿壁的横截面图像，并提供了详细的病理学信息。它在诊断和指导方面具有显著的优势，并已从冠状动脉介入治疗逐渐引入到更广泛的血管内手术中。然而，IVUS 本身并不能为其生成的图像提供空间姿态信息，因此很难构建 3-D 血管内可视化。为了解决这个限制，已经开发了基于 IVUS 成像的 3-D 血管内重建技术。这些技术可以实现血管内疾病的准确诊断和定量测量，从而有助于确定最佳治疗方案。这种重建将 IVUS 成像模式从单纯的诊断辅助扩展到术中导航和指导，并支持治疗选择和介入操作。本文全面综述了基于 IVUS 成像的 3-D 血管内重建技术及其最新应用的技术进展和最新进展。还讨论了现有技术的局限性和新技术的前景。
