How can I use the DICOMWRITE function to save a in MATLAB generated contour as a DICOM file? (Modality RTSTRUCT)

I would like to be able to use the DICOMWRITE function to save my current contour (an array of x y and z coorinates of points) as a DICOM file. Or alternatively to edit one of the structures of the original dcm file (Modality RTSTRUCT). Thanks for your help!

Hi everyone!

I managed to edit and add new contours to the metadata of the dicomfile.

I used dicominfo to edit the data

(e.g.info.ROIContourSequence.(NewItem).ReferencedROINumber = NumberOfROIs; %adapting the refROINumber in a loop)

and dicomwrite to save the altered data to a new file.

(e.g. dicomwrite([ ],[inputnewfilename '.dcm'], info, 'CreateMode', 'Copy') )

So far, so good...

A problem occurs when I try to import the new generated file back to the treatment planning system. It cannot read it ("file is not a dicomfile"?!) or complains that something's wrong with it. I suppose that the default image data dicomwrite is saving to it (e.g. Width=0, Height=0, BitDepth=16... instead of [ ]) is confusing the system, so that it cannot recognize it as structure-file.

I really need your help. Do you know how one can change this default values?

Thanks in advance!
