[Insight-users] Support of IPP and IOP in ImageViewer.

[Luis Ibanez]

Hi Yoav,


1) Please us the example application:

       Insight/Examples/IO/DicomSeriesReadImageWrite2.cxx

    to convert your DICOM series to MetaImage.



2) What tool are you using for checking the coordinates ?

       ParaView ?
       Slicer ?


3) We cannot confirm much about the coordinates differences
    that you are reporting, unless we have access to the
    DICOM series that you are using. Can you make it available ?


4) ITK is Open Source  :-)

    You will find the most recent version of
    the ImageViewer under:

       InsightApplications/ImageViewer


5) Before concluding that the ImageViewer is using an
    incorrect coordinate system, you should load your
    DICOM dataset *and* the converted MHA image in an
    application that manages orientation correctly.

    The best application in this regard is Slicer

           http://www.slicer.org/

    Slicer will display correctly an image, by taking
    into account, both its origin, spacing and orientation.


Please upload you DICOM image into Slicer and let us
know what you find,


     Thanks


        Luis
