containing the spine. Different strategies are included to 
handle images where only part of the spinal column is visible. 
The algorithms require one seed point given on a slice located 
in the middle region of the spine, and the rest is automatic. 
The spatial extent of the spinal cord/canal is determined 
automatically using anatomical information for segmenting the 
spinal canal while active contours are applied if the spinal 
cord is to be segmented. Both methods work in 2D and use 
propagated information from neighboring slices. They are also 
very rapid in execution, that means an efficient, user-friendly 
workflow. The methods were evaluated by radiologists and were 
found to be useful and met the accuracy and repeatability 
requirements for the particular task.
