Overview of geometric shapes of selected structures in the shoulder and arm

 

H.E.J. Veeger, B. Yu


All data are given in the measurement coordinate system. This system roughly corresponds with the Z-axis vertically upwards, the Y-axis horizontally forward and the X-axis horizontally outward. Of course, these data can be transformed to any coordinate system with the use of the anatomical landmarks. The coordinates of these landmarks are given in the XYZ-files (see the Introduction for an explanation of the methods)
