Automatic bone segmentation technique for CT angiographic studies.
OBJECTIVE
The purpose of this work was to develop and evaluate an automatic bone segmentation technique for CT angiographic studies.


METHODS
An automatic bone segmentation scheme was developed and applied to 40 CT examinations. The results of the segmentation were evaluated subjectively by two radiologists.


RESULTS
The bone segmentation was, on average, rated between excellent and good. Automatic segmentation required approximately 25 s/case.


CONCLUSIONS
With this high quality technique, bone can be segmented easily and accurately and subsequently can be removed from CT data sets for further 3D visualization and analysis of various organs.
