[Insight-users] Re: Volume Dataset - headsq in ITK VTK Example

[Luis Ibanez]

Hi Sharef,


          Google is an amazing tool.

If you type:


               "headsq itk"


The third link is the following email of the ITK users list
http://public.kitware.com/pipermail/insight-users/2003-May/003894.html

Where you will find the MetaImage header that allows you to read
the headsq dataset with an itk::ImageFileReader.

filename="quarter.mhd":


NDims = 3
DimSize = 64 64 93
ElementSpacing = 1 1 1
Position = 0 0 0
ElementByteOrderMSB = False
ElementType = MET_USHORT
ElementDataFile = quarter.%d 1 93 1




Note that the actual demo that you are looking at is an early
experiment where ITK filters where wrapped inside VTK filters.
In that situation, the reading of the image is done with VTK
filters.


I would suggest you to use the MetaImage header attached and
look at the ITK registration applications such as


     InsightApplications/
          LandmarkInitializedMutualInformationRegistration


Once you load an image in ITK you can save it in any
of the formats listed on the FAQ

   Regards,
