vstnm − sternum segmentation
SYNOPSISvstnm if= [zr=] res= of= [-i] [-v] [-d]
DESCRIPTIONvstnm segments the sternum from a non-contrast chest CT scan. The inputs include an organ map with segmented right clavicle (as 1), left clavicle (as 2), airway (as 3) and bone candidates (as 255). The coordinates of landmarks of the clavicles are specified in the input zr=seedRZ,seedLZ,antRZ,antLZ, where seedRZ and seedLZ are the z coordinates of right and left clavicle seeds; antRZ and antLZ are the the z coordinates of the right and left anterior clavicle ends. If -i is specified, then the program works assuming no clavicles are segmented, thus zr= are not needed, which is the case for CT scans starting at an inferior axial level to clavicles.
vstnm first identifies a seed cross section based on the spatial constraints defined by the segmented clavicles and airway. The a sequential region growing algorithm is applied in the superior and inferior direction respectively.
