vsternum − clavicle segmentation
SYNOPSISvsternum if= im= [zr=] of= [-i] [-v] [-d]
DESCRIPTIONvsternum segments the sternum from a non-contrast chest CT scan. The inputs include the CT scan and the organ map with segmented airway and clavicles. The output is the updated organ map with the segmented sternum added. 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.
vsternum first identifies the bone candidates based on thresholding and noise filtering. It then calls vstertrack for sternum segmentation.
