磁共振成像（MRI）是动脉粥样硬化风险评估的一种方式，它允许将颈动脉斑块分为高风险或低风险病变。虽然MRI通常用于观察动脉粥样硬化对血管管腔的影响，但它也可以显示其本身的大小和组成，以及斑块信息，从而提供单纯狭窄之外的信息。软件系统在颈动脉狭窄评估中是一个有价值的辅助工具，其中商业软件很容易获得，但并非所有从业者都可以使用，因为它通常成本很高。本研究的重点是开发一个软件系统，完全用于注册，标记和三维可视化的墙壁和流腔，使用免费的开源工具和库。它的设计目的是避免“功能膨胀”和“功能蠕变”。改进后的QDCM库的图像加载和显示模块至少提高了10,000%。使用Bezier函数通过在标记点之间插入额外的点来平滑多边形的曲线（指由标记点形成的形状）。这条平滑的曲线使腔体和壁的3D视图更加平滑。
Magnetic resonance imaging (MRI) represents one modality in atherosclerosis risk assessment, by permitting the classification of carotid plaques into either high- or low-risk lesions. Although MRI is generally used for observing the impact of atherosclerosis on vessel lumens, it can also show both the size and composition of itself, as well as plaque information, thereby providing information beyond that of simple stenosis. Software systems are a valuable aid in carotid artery stenosis assessment wherein commercial software is readily available but is not accessible to all practitioners because of its often high cost. This study focuses on the development of a software system designed entirely for registration, marking, and 3D visualization of the wall and lumen, using freely available open-source tools and libraries. It was designed to be free from “feature bloat” and avoid “feature-creep.” The image loading and display module of the modified QDCM library was improved by a minimum of 10,000%. A Bezier function was used in order to smoothen the curve of the polygon (referring to the shape formed by the marked points) by interpolating additional points between the marked points. This smoother curve led to a smoother 3D view of the lumen and wall.
