[Insight-users] Convert dicom image to other format

[Frank Zhao]

The volume type is:

  typedef signed short   PixelType;
  typedef itk::Image< PixelType, 3 >                VolumeType;

The DICOM files is CT image data.

I use both snap and volview to view the result MetaImage file.

Accurely, it is not corrupted, it still show as a 3D image, but like a biany 
image of the original one, I check the voxel value, it is not biniary image. 
with some voxel value goes up to 60000 and some only around 50, look like a 
bianary image.

I modified the ISIS demo source for DICOM files( project name: 
APPLICATIONMODEL, following the cvs download provided by you), it displays 
DICOM image correctly, I only  add the writer code after DICOM image is 
loaded.

When DICOM is readed, it uses signed short as the image type.

Thank you Luis

Frank
