<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>It is me again. I got some progress. When I added the
following sentence to realice2 and reslice3. Finally I can see part of the image
in some slices. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>
reslice3->SetOutputExtent(0,255,0,255,0,255);<BR>
reslice3->SetOutputSpacing(1, 1, 1);</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>It seems that the images are not on the center of the
viewer. I guess the reson is wrong rotation origin. but I do not know how to set
it. Also the output is not correct.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [vtkusers] How to SetDataOrigin
when I use vtkImageReslice to getsagittal and coronal images?</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I want to get axial, sagittal and coronal images
from a series of dicom files. And then get the 3D coordinate of a point
in the image.</FONT><FONT face=Arial size=2> Now I can see the axial
image. But The sagittal and coronal images seem not correct. Most of them are
black. I can only see a band on sagittal's bottom and coronal's
left in few slices. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>(1) I guess the reason is I did not use
SetDataOrigin function. I tried but do not know how to choose the parameters.
And when I use SetDataOrigin, the program become very slow.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(2) In the sample program, a vtkVolume16Reader is
created to read the Dicom files. I got a error:</FONT></DIV>
<DIV><FONT face=Arial size=2>ERROR: In E:\vtk-5.0.3\IO\vtkVolume16Reader.cxx,
line 384<BR>vtkVolume16Reader (0x023250E0): Error reading raw pgm
data!</FONT></DIV>
<DIV><FONT face=Arial size=2>So I use vtkDICOMImageReader to read the dicom
images. Is it a problem?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(3) Is there any other parameters to be
set?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
