<DIV><FONT face=Arial size=2>Hello!!!!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've questions about the data found at <A
href="ftp://public.kitware.com/pub/itk/Data/MultiFieldMRI/HighField">ftp://public.kitware.com/pub/itk/Data/MultiFieldMRI/HighField</A>.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>* What is the difference between e1 and e2 ? e2
seems just the same but 'darker' ... ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>* what are the resolution of the slices? Are they
16 bits or 8 bits image files? how to know? what about 'dataspacing'?
what's the difference between 'Data byte order = little endian and big
endian'?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>* should I use vtkvolume16reader or
vtkvolumereader instead of vtkimagereader? what are the differences?
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>* I obtained a view of the slices using the
code below, the result is good but on the sides the
images are deformed .... anybody knows why ???</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you very much for help,</FONT></DIV>
