STAPLE: Shared Tools for Automatic Personalised Lower Extremity modelling

STAPLE requires three-dimensional bone geometries as an input. These geometries are normally surface models segmented from medical images like magnetic resonance imaging (MRI) or computed tomography (CT) scans. STAPLE performs morphological analyses on the provided bone geometries and defines reference systems used to create models of entire legs or few joints, depending on the available data or the research intent. Currently the toolbox creates kinematic and kinetic skeletal models but will soon be extended with complete musculoskeletal capabilities.Using STAPLE is currently possible to perform the following operations:<ul> <li>Creating complete skeletal models of the lower limb from segmented bone geometries with provided workflows or customizable degrees of freedom for the joints.</li> <li>Creating partial skeletal models of the lower limb. For example models of hip, knee and ankle joints can be created as individual models.</li> <li>Extracting the articular surfaces of the lower limb joints, for example the tibiofemoral articular surfaces.</li><li> Merging generic and personalised models.</li><li>Basic identification of bony landmarks, intended as first guess for registration with gait analysis motion capture data.</li></ul> <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=1942#pack_2224">STAPLE Toolbox </a> : This package includes STAPLE, acronym for Shared Tools for Automatic Personalised Lower Extremity modelling, a MATLAB toolbox to create models of the lower extremity from subject-specific bone geometries automatically and in negligible processing time. </li> </ul>

STAPLE系统需以三维骨骼几何形状作为输入。此类几何形状通常源自于医学图像，如磁共振成像（MRI）或计算机断层扫描（CT）的表面模型分割。STAPLE系统对提供的骨骼几何形状执行形态学分析，并定义用于构建整条腿或少数关节模型（依据可用的数据或研究目的）的参考系统。目前，该工具箱能够创建运动学和动力学骨骼模型，并即将扩展其功能，以包含完整的肌肉骨骼能力。利用STAPLE系统，目前可以执行以下操作：
<ul>
<li>基于提供的流程或可自定义的关节自由度，从分割的骨骼几何形状中创建完整的下肢骨骼模型。</li>
<li>创建下肢部分骨骼模型。例如，可以单独创建髋关节、膝关节和踝关节的模型。</li>
<li>提取下肢关节的关节面，例如胫股关节面。</li>
<li>合并通用模型与个性化模型。</li>
<li>对骨骼标志进行基本识别，旨在作为与步态分析运动捕捉数据配准的初步猜测。</li>
</ul>
