Biplane fluoroscopy derived humerus and scapula kinematics during arm elevation and rotation

This dataset contains torso, scapula, and humerus kinematics from 20 healthy subjects performing coronal plane abduction, scapular plane abduction, forward elevation, internal external rotation at 90º of abduction, and internal external rotation in adduction. The humerus and scapula were imaged at 100 Hz using a biplane fluoroscopy system. 3D models of the humerus and scapula were constructed from each subject’s CT scan. Model-based markerless tracking ascertained the 3D position and orientation of each bone model by semi-automatically aligning digitally reconstructed radiographs against each frame of the biplane fluoroscopy recordings. The kinematics of the torso were measured using skin marker motion capture.本数据集涵盖20名健康受试者完成冠状面外展、肩胛面外展、肩关节前屈、外展90°位内外旋转以及内收位内外旋转动作时的躯干、肩胛骨（scapula）及肱骨（humerus）运动学数据。研究采用双平面透视系统（biplane fluoroscopy system）以100 Hz的采样频率对肱骨和肩胛骨进行成像；基于每位受试者的CT扫描结果构建肱骨与肩胛骨的三维模型。基于模型的无标记跟踪技术通过将数字重建放射影像（digitally reconstructed radiographs）与双平面透视记录的每一帧进行半自动配准，确定了每块骨骼模型的三维位置与姿态；躯干的运动学数据则通过皮肤标记点运动捕捉系统采集。
