[Insight-users] Create 3D image data by a series of 2D dicom files

[Luis Ibanez]

Hi Jiang,

Thanks for sending the DICOM slice that is giving you
trouble.

The good news is that it works just fine when I loaded it
with the ImageViewer application. (from InsightApplications).

I think that the real suspect at this point are other
spurious files that you may have in the same directory.
The DICOMSeriesFileNames is basically assuming that *ALL*
the files in the directory are DICOM slices. Potentially
from different series, but still all of them being valid
DICOM files.


My guess is that the message:

 >>>No DICOM magic number found, but file appears to be DICOM.
 >>>Proceeding without caution.

is produced when the DICOMSeriesFileNames encounter
other non-DICOM files in your directory and attempt to
interpret them.

Could you please do the following simple experiment ?

    move a set of DICOM slices to a new directory and
    make sure that they are all valid slices.  You could
    use MRIConvert (from Jolinda Smith), or VolView from
    Kitware, in order to verify the set of selected slices.




Please let us know what you find.


   Thanks


     Luis
