Thanks a lot Henrik, it is very helpful and interesting. I am able to extract the boundary of the Dicom Format image.

With img being the top image you can try things like:

Binarize[img, 0.95]
DeleteSmallComponents[%]
ColorNegate[DeleteSmallComponents[ColorNegate[%]]]
MorphologicalPerimeter[%]
ComponentMeasurements[%, "Contours"]
