This paper purposes an automatic method for bone
segmentation in the pelvic region based on in-phase and
out-of-phase images acquired on a reduced TE through the
use of a custom designed spectral-spatial selective
excitation pulse. A segmentation bone mask is obtained
through a k-mean algorithm and compared with a similar
mask calculated on reference in-phase and out-of-phase
images. The suggested method shows an improvement in the
false positive reduction in the bowel area compared to
the reference bone mask and is eligible to produce good
Digitally Reconstructed Radiography.
