One of the CT volumes is referenced as the neutral position. This volume is manually segmented via the Analyze software package in order to extract the bone surfaces. These bone surfaces are represented by discrete points and are used for the automated registration of the remaining positions.
A Technical Note
The list of points that define contours for each bone component in each slice are stored as files with the extension ".stack". In at least one example, from a subject's root directory the .stack files are in the subdirectory:
<subject-data-root>/original_stacks/S15L/*.stack <subject-data-root>/original_stacks/S15R/*.stack
These files are only defined for pose/scan #15 which is defined to be and referred to as the neutral position.
