In this work, we propose a method for segmentation of
bones in the head using a single echo zero TE (ZTE)
pulse sequence using complex (magnitude and phase)
information for efficient segmentation of bone and air
regions in the head. We also introduce a histogram-based
RF intensity correction method which enables
threshold-based segmentation of bone, soft-tissue and
air structures. We demonstrate excellent depiction of
skull and vertebrae.
