[Insight-users] Bug in DicomSeriesReadSeriesWrite ??

[Johnson, Hans J]

Are you reading into a 2D image?  A 2D image only stores 2D origin, spacing, etc.

If you want to preserve the 3rd dimension, you will have to read a single slice into a 3D image.

I am just guessing that this might be the problem.

Dear ITK users,

I'm playing with DicomSeriesReadSeriesWrite, but I noticed that values in tags
"ImagePositionPatient" and "ImageOrientationPatient" were not restored correctly.
should be:
(0020,0032) DS [112.81570415012\-115.84296800997\110.38483167658]
(0020,0037) DS [-0.0484719045791\0.99882454638764\2.34458564e-008\-0.1526400678013...
but I got:
(0020,0032) DS [112.81570415012\-115.84296800997\0]    <-- z-value is 0 for all slices
(0020,0037) DS [1\0\0\0\1\0]

Is it a bug in DICOM IO ?
Any suggestions would be greatly appreciated !!!
Thanks in advance.
YIYU
ps. I'm running itk4.2
