[Insight-developers] Reading an ITK Image from multiple files in a Directory

[Stephen Aylward]

MetaImage format can handle this.

Create a file in a top level directory call   Image.mhd

In that file, put the following text

NDims = 3
DimSize = XXX YYY ZZZ
ElementSpacing = 1 1 1
Positions = 0 0 0
ElementByteOrderMSB = Flase
ElementType = MET_UCHAR
HeaderSize = -1
ElementDataFile = LIST
<first slice filename>
<second slice filename>
...


Replace the XXX YYY and ZZZ with the size of the final image.   XXX
YYY should be the size of each slice.   ZZZ should be the number of
slices.    All are in units of pixels.

Replace the 1 1 1 for elementSpacing if you know the between-pixel
distance of your image, i.e., is the spacing between slices equal to
the spacing between increments in the x and y dimensions?

Replace the MET_UCHAR with MET_CHAR, MET_USHORT, MET_SHORT, MET_INT,
MET_FLOAT, .... as appropriate for your data.   Note that your data
cannot be compressed data.   It must be in the "raw" format.

Then add the filenames below the LIST keyword.

Hope this helps.
