[Insight-users] Problem in copying DICOM image: Study instance UID value is changed

[Subrahmanyam Gorthi]

Dear Mathieu,

Many THANKS for your detailed & prompt reply.

Here is what I am actually trying to implement in ITK:

Using a segmentation algorithm in ITK, I obtained the coordinates for 3-D
ROI of a patient's image .
I am now trying to export these results into a "DICOM-RT Structure-Set"
file, for RT-Planning in IMRT.

In addition to ROI module, as the DICOM-RT structure-set file has to contain
other
mandatory modules like patient-module, study module etc.,
I am trying to selectively copy those modules from the associated patient's
3-D CT image.

I compared the tags of structure-set file that I am creating in ITK with
the  file generated by another software that
a Physician here is using in his hospital;
he was manually drawing the contours on the CT image and the corresponding
DICOM-RT structure-set file is generated by the software.

I observed that for the "structure-set" file generated by that software,
"study-instance UID" tag is same as that of the
other 3-D CT DICOM images and hence, I am trying to do the same for the file
created through ITK.
