Hi,
We are using itk to read Mr images. No problem with native images, all works
fine.
We recently ran into trouble with secondary Mr images. These images are
created from native ones, the only change is the pixel type which is
converted from Unsigned-16bits to RGB.
Allthough all the required data to compute the local to real world matrix
are available (PixelSpacing/IIP/IOP/SliceThickness), the matrix is set to
identity, as if gdcm do not read these data because image is of type
secondary (modality is MR).
Is this the correct behavior of the reading process ? I m a bit surprise
because I could manually set the matrix so why doesnt the reader ?
Is there a way to easily correct gdcm to handle correctly these images ?
Thanks
Vincent
