[ITK-users] Vessel Segmentation

[Matt McCormick]

Hi Nissim,

I would suggest reading in the DICOM data with an ITK reader as an ITK
Image and writing out the output in an ITK supported file format, at
least until the source of the problem is determined.  There are many
errors that can occurs when passing around blocks of bytes.

HTH,
Matt
