DICOM Files acting flakey in Image viewers after anonymization : <p>I wrote my own version of DICOM Anonymizer with python. I have a set of tags that have to be anonymized, including <code>Frame of Reference UID</code>, <code>Series Instance UID</code> and <code>SOP Instance UID</code>. Changing these to random values as a way of anonymizing seems to be breaking the way images for one patient is being shown as a volume, or in some cases image viewers like Clear Canvas don't even open the files.</p>

<p>I know some of the Anonymizers available to use do hash these tags. My question is how can I do that and keep the dicom files intact.</p>

<p>Also, I am pretty new to DICOM so if someone could explain what would not having those tags anonymized give away as sensitive information would be great.</p>

<p>Thanks.</p>
