[Insight-users] Incorrect origin and spacing when converting DICOM to metaimage

[Mengda Wu]

Hi all,

  I have some dicom images in my new project. But when I tried to convert
them to the ITK metaimages, the origin and spacing are incorrect even
though the intensities are right. The origin becomes (0,0,0) and spacing is
(1,1,1). I am the example
DicomSeriesReadImageWrite2.cxx<http://itk.org/gitweb?p=ITK.git;a=blob_plain;f=Examples/IO/DicomSeriesReadImageWrite2.cxx;hb=HEAD>



from ITK 4.4.2. The code does not have any issue with other Dicoms for my
previous projects. so my guess is the current dicoms miss some fields in
the header that ITK needs.

Can you help? I am attaching the fields from one dicom as follows:
