SIEMENS Healthineers CLEARstent & CLEARstent Live应用简介 功能介绍 一 1）ClearStent 图像功能，可以增强纤细结构显示，如膨胀的支架。通过平均化一个序列 的若干帧图像以及兼顾到支架标记的对齐，可以创建合成图像。 2) ClearStent Live 序列，将提供支架的实时稳定显示。 0:57:28 AM 16 - 1/36 ClearStent造影剂充盈显示效果 ClearStent支架解构显示效果 0/23/2019 HFS 04:16 PM /com///E/S/ - 36/48 21 sec ClearStent Live在支架对位时实时稳定显示 learStent live ClearStent Live在支架对位时稳定显示 EE 20% ODO 60% n 22 101 AO 16º / CRAN 29º 2.应用选择 1）CLEARstent 2）CLEARstent Live •可进行后处理操作 •实时采集序列 •尽可能提高图像质量观察单个支架 •查看支架与心脏解剖位置的关系， •评估支架使用情况，例如支架展开的区域 •优化支架定位 •提供临床参考 •在消除心脏运动的同时，优化图像质量 Job Aid | CLEARstent & CLEARstent Live应用简介 Unrestricted | Effective Date: 2020-05-15 | HOOD05162003087449 https://www.siemens.com/pepconnect SIEMENS Healthineers CLEARstent and CLEARstent Live 原理 它利用动态校正的X线透视显影技术，自动根据动态补偿采集的连续帧图像叠加转换成 数字电影来显影支架，以增强植入冠脉支架的可视性，有助于检测支架的扩张和血管贴壁 情况。 Register& Average Frames O A B Original I ranslation Rotation Scaling Job Aid | CLEARstent & CLEARstent Live应用简介 Unrestricted | Effective Date: 2020-05-15 | HOOD05162003087449 https://www.siemens.com/pepconnect SIEMENS Healthineers CLEARstent and CLEARstent Live临床应用 IMAGES IN INTERVENTION Stent Deformation in Bifurcation Stenting With Final Kissing Balloon Inflation In Vivo Demonstration With Enhanced Cine Fluoroscopic Imaging Stephan Achenbach, MD, Christian Schlundt, MD Erlangen, Germany Various techniques for stent deployment in bifurcation lesions have been developed. In gen- given the poor x-ray absorption of modern thin- cral, a single-stent approach is preferable, but strut stents. Software tools have become available balloon dilation of the side branch can lead to that permit improved visualization of coronary deformation of the main branch stent, which is stents in cine fluoroscopy. They improve contrast- incompletely resolved by "final kissing balloon to-noise ratio (and, hence, resolution) by aver- dilation" (1,2). In vivo imaging of stent expansion aging consecutive cine fluoroscopic frames. Balloon markers are used as reference points in and deformation by fluoroscopy is challenging, order to eliminate motion. We present cine fluo- roscopic images obtained using a commercially available stent enhancement tool (ClearStent, LAO 10 CRAN 44 Siemens Healthcare, Forchheim, Germany) on a single-plane x-ray angiographic flat panel system (Artis Zee, Siemens Healthcare).
