IVUS is a catheter-based imaging technology that allows visualization of vessels from the inside out. Cross-sectional images help assess presence and extent of disease, plaque geometry and morphology, guide wire position during lesion crossing, and stent position post-treatment.

Philips intravascular ultrasound (IVUS) imaging offers advanced visualization that enables you to decide the best therapy option, guide pre-stent planning and optimize treatment results. Discover how Philips IVUS benefits your treatment plans in coronary and peripheral interventions.

2022年8月13日 · 血管内超声（Intravascular ultrasound，IVUS）是一种血管内的成像方式，可用于各类介入学科，以表征病变形态、量化斑块负荷、指导器械尺寸选择、评估器械植入以及识别并发症。 IVUS作为斑块诊断最常用的成像技术，可提供分辨率约为100微米，成像深度约为7毫米的血管横截面结构图像， 但无法显示与斑块易损性相关的微观特征，譬如新生血管、巨噬细胞聚集和薄纤维帽等。 IVUS在经皮冠状动脉介入 ( percutaneous coronary intervention,PCI)手术中可 …

This feature also provides automated, real-time side-by-side display of co-registered IVUS and angio images to help correlate critical and anatomical landmarks, especially in complex cases, such as bifurcations.⁴, ⁷, ¹⁰, ¹¹

目前，新一代的IVUS-NIRS可以在IVUS基础上对斑块的脂质成分进行分析；IVUS-OCT融合技术可以将OCT的高分辨率，对钙化斑块的良好穿透性与IVUS的对血管管壁的良好穿透性结合起来；OCT-NIRS则可以在OCT良好显示血管结构的基础上分析斑块的脂质成分。 以上内容和图片来自2017年Mintz等人的综述，三年内可能已有新产品新技术问世，如有不准确的地方，欢迎讨论和指正。 参考文献. Mintz GS, Guagliumi G. Percutaneous Coronary Intervention 2. Intravascular …

octivus试验在韩国9个研究中心开展的一项前瞻性、多中心、随机、开放标签研究，旨在对比oct和ivus指导的pci治疗的疗效。按1:1的比例将2008例患者进行随机分组，分为oct指导组和ivus指导组。

血管内超声 （Intra Vascular UltraSound，IVUS）技术诞生于20世纪末，它利用安装在心导管顶端的微型超声探头，实时显示血管的截面图像，能清晰显示管壁结构的厚度、管腔大小和形状等，精确地测量血管腔径及截面积，甚至可以辨认钙化、纤维化和脂质池等病变 ...

The Eagle Eye Platinum digital IVUS catheter system is compatible with SyncVision co-registration which creates a three-way association between locations on the angiogram, longitudinal IVUS display, and tomographic IVUS frames. SyncVision simplifies vessel sizing, streamlines lesion assessment, and enables precise therapy delivery.

VH IVUS* imaging can provide a more detailed and objective view of plaque composition (see pages 23-24). The calcium in this plaque produces two arcs of acoustic shadowing. Calcium is indicated by very bright areas with acoustic shadowing that blocks out the image behind.

2023年8月15日 · 血管内超声-光学双模成像系统（IVUS-OCT）是一种结合了血管内超声成像（Intravascular Ultrasound，IVUS）和光学相干断层扫描（Optical Coherence Tomography，OCT）两种显像技术的医疗设备，用于血管内的影像采集和诊断。
