Quantification of regional cardiac function is a central goal of cardiology. Multiple methods, such as Coherent Point Drift (CPD) and Simultaneous Subdivision Surface Registration (SiSSR), have been used to register meshes to the endocardial surface. However, these methods do not distinguish between cardiac chambers during registration, and consequently the mesh may "slip" across the interface between two structures during contraction, resulting in inaccurate regional functional measurements. Here, we present Multilabel-SiSSR (M-SiSSR), a novel method for registering a "labeled" cardiac mesh (with each triangle assigned to a cardiac structure). We compare our results to the original, label-agnostic version of SiSSR and find both a visual and quantitative improvement in tracking of the mitral valve plane.
区域心脏功能的量化是心脏病学的核心目标。多种方法，如相干点漂移（CPD）和同步细分曲面配准（SiSSR），已被用于将网格配准到心内膜表面。然而，这些方法在配准过程中无法区分心脏腔室，因此在收缩过程中，网格可能会在两个结构的界面上“滑动”，导致区域功能测量不准确。在此，我们提出了多标签SiSSR（M-SiSSR），这是一种用于配准“标记”心脏网格（每个三角形都分配给一个心脏结构）的新方法。我们将我们的结果与原始的、无标签的SiSSR版本进行比较，发现二尖瓣平面的跟踪在视觉和定量方面都有改进。
