[Insight-users] how to save a dicom file after processing with its original header infomation

[Luis Ibanez]

Hi Chris,

What exactly was changed in the image content (the pixel data) ?

Did the intensities of the pixels changed ?

What was the pixel type of the original data ?

What was the pixel type that you used for
instantiating the itk::Image<> in your code ?


If you instantiate the image using the correct pixel type,
then the values should not change.

What tool are you using for looking at the DICOM image
pixel data ?



   Please let us know,


     Thanks



        Luis
