Replace an image with other one

[Helder Cesar]

Hi!

I want to replace an image of an dicom file for an image of other dicom file.
After opening both files, _file1 and _file2, what I'm doing is:

    DicomFile new_dicom = _file1;
    DicomImage img = new DicomImage(_file1.Dataset);
           
    new_dicom.Dataset.Remove(DicomTag.PixelData);
    new_dicom.Dataset.Add(DicomTag.PixelData, img.PixelData);

    new_dicom.Save("newfile.dcm");

For some reason, the program stops at line 5 (...Add(DicomTag.PixelData...)
What am I doing wrong?
Comments and suggestions are welcome.

Thank you.

So you want to create a copy of an image in disk?

Actually I want to copy all header information of one file to another one.
Since I didnt find any way to copy the header in a single way, I supposed is easier to copy the image of one to another...

  Try this:

         DicomImage img = new DicomImage(_file1.Dataset);

                DicomFile archivodicom = new DicomFile();

                archivodicom = new DicomFile(img.Dataset);

                archivodicom.Save("newfile.dcm");

Hi.

Sorry but, this code doesnt make any sense!

For example, in the code below You already have a new instance of DicomFile, why should you do another new instance based on img.Dataset?

DicomFile archivodicom = new DicomFile();
archivodicom = new DicomFile(img.Dataset);

Look, perhaps I didnt make myself clear:

This is the situation:

_file1;
_file2;

_newfile = _file2;

// Copy Image from _file1 to _newfile. So this _newfile will have the header of _file2 but the image of _file1.

_newfile.Save("newfile.dcm");
