[Insight-users] WG: Question about loading volume by ApplicationModel

[Luis Ibanez]

Hi Jiang,

You don't need to change the Callback of the "Load" button.

There is another button labeled "Load DICOM" that is associated
to the "LoadDICOM()" call back. Simply move this button to the
visible are in your screen.


We already discussed in previous emails the reasons why
you are getting the messages:

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

http://www . itk . org/pipermail/insight-users/2003-October/005116 . html

Your DICOM files are not fully compliant with the standard.
They are missing the preamble.


---

ITK has two DICOM readers:  DICOMImageIO  and DICOMImageIO2.

DICOMImageIO = will read your non-compliant images without
                reporting any error messages

DICOMImageIO2 = is more stringent in testing the format, and
                 reads your images but prints out the error
                 messages indicating that the images are not
                 quite right.


You can live with the error messages, ....or you can replace
the ITK DICOM reader in line 112 of DicomImageReader.txx

replace:

  itk::DICOMImageIO2::Pointer  dicomImageIO =
                                  itk::DICOMImageIO2::New();

with:

  itk::DICOMImageIO::Pointer  dicomImageIO =
                                  itk::DICOMImageIO::New();




   Regards,


   Luis
