Visualization of intermediate steps in generating the high-resolution scapula model from multiple MRI planes. The blue crosshair indicates the same glenoid position across all views. (a) In-plane distance map of the scapula segmentation on coronal, transverse and sagittal MRI planes, with distances ranging from − 15 and 15. Bright areas represent high segmentation border distances within the scapula mask, while dark areas indicate large distances outside the mask. (b) Mask border consistency along the out-of-plane direction in the coronal, transverse and sagittal MRI planes, ranging from 0 and 1. White areas denote regions with low border consistency (assigned lower weighting for plane-combination), while dark areas indicate regions with higher consistency and weighting.
