Measures of scapulothoracic motion are dependent on accurate imaging of the scapula and thorax. Advanced radiographic techniques can provide accurate measures of scapular motion, but the limited 3D imaging volume of these techniques often precludes measurement of thorax motion. To overcome this, a thorax coordinate system was defined based on the position of rib pairs and then compared to a conventional sternum/spine-based thorax coordinate system. Alignment of the rib-based coordinate system was dependent on the rib pairs used, with the rib3:rib4 pairing aligned to within 4.4 ± 2.1 deg of the conventional thorax coordinate system.
肩胛胸壁运动的测量依赖于肩胛骨和胸廓的精确成像。先进的放射成像技术能够提供肩胛骨运动的精确测量,但这些技术有限的三维成像范围常常使胸廓运动的测量无法进行。为克服这一问题,基于肋骨对的位置定义了一个胸廓坐标系,然后将其与传统的基于胸骨/脊柱的胸廓坐标系进行比较。基于肋骨的坐标系的对齐取决于所使用的肋骨对,其中第3肋:第4肋的配对与传统胸廓坐标系的对齐误差在4.4±2.1度以内。
