DICOM anonymizer

[Primoz Peterlin]

Hello,

First of all, I would like to praise dicompyler in general, as well as its use as a DICOM anonymizer. However, when I recently had to anonymize a set of DICOM files, I found out that in one of them, apart from the ReferringPhysicianName (0008,0090) field, which gets properly anonymized, the field PhysiciansOfRecord (0008,1048) has also been filled-in, and was not anonymized. I suggest that in one of the next releases, this field is also included for anonymization.

All the best, Primož

[Adit Panchal]

Dear Primož,

Thank you for the kind words. I will consider adding the field you suggested to the anonymization process.

Also for consideration would be allowing the user to specify any tags on demand that they would like to be anonymized.

Thanks,

Adit

Dear Adit,

If you want to be thorough, DICOM Supplement 142 "Clinical Trial De-identification Profiles" is probably a good start.

All the best, Primož

Hi there are a couple of other fields which I require to complete anonymisation, these are SOP, Study and Series Instance UID. Would be useful to replace these with a random unique value. I have spent an hour trying to edit and build the python code but have been unsuccessful owing to inability to install version 2.8 of wxpython. Thanks

[Adit Panchal]

If you are using the binary (exe) version, you can just replace anonymize.py with an edited copy and it will take precedence over the included one. You can add in the fields you require in the list.

I will update the existing issue here: https://github.com/bastula/dicompyler/issues/45 for the case of UID anonymization.

Thanks for the suggestion.

Hi Aditya:

I am trying to modify the anonymize.py source file to avoid some tags to be anonymized. I wanted to substitute the anonymize.py file in the exe binary version, as you suggest, but in the version I have (0.4.2), there is no anonymize.py, but a compiled anonymized.pyo. I am a beginner in python, and I do not know how to create a compiled version. Can you give some hints on what to do?
Thanks and good work!

Marcelino Hermida

[Aditya Panchal]

Hi Marcelino,

Actually you can just place your updated copy of anonymize.py in the same folder as anonymize.pyo. The Python interpreter inside of dicompyler will create an updated version of anonymize.pyo once you re-run the application.

If that doesn't work, you can go to Tools, Options and locate the User Plugins folder. You can place your file there as well, as it will override the default plugins.

Hope that helps,

Adit

Hi Adit:
Thanks! That worked perfectly, much easier than I had expected. You did a great work with dicompyler.
Regards,
Marcelino

Glad to hear that it worked for you! Thanks for the kind words!

Hi Aditya,

I am trying to do the exact same thing as Marcelino and tried both of your methods:

1. Drop anonymize.py in the plugins folder.
2. Drop anonymize.py in the dicompyler\baseplugins installation folder.

In both cases I see a new compiled file after restarting dicompyler. But when I try to anonymise a patient the export option is greyed out. This even happens when I use the original anonymize.py without modifying it.

The log file contains the following:

2017-11-08 13:36:34,858 - dicompyler.plugin - ERROR - anonymize could not be loaded

Traceback (most recent call last):

  File "dicompyler\plugin.pyo", line 51, in import_plugins

  File "C:\Users\Wenze\AppData\Local\dicompyler\plugins\anonymize.py", line 13, in <module>

ImportError: cannot import name pub

That seems to indicate that wxpython is not installed, which I verified it worked.

After that I tried it on a fresh Virtual Machine to make sure that Python wasn't have a problem with dependencies. I installed Anaconda Python 2.7 + WxPython but still run into the same error.

Any ideas?

Thanks,

Wenze

[Aditya Panchal]

Hi Wenze,

Are you replacing anonymize.py with the one from the latest version from master branch on GitHub? If so, that version requires updated wxPython dependencies, which the 0.4.2 binary version does not have. It is still using wxPython 2.8.10.1 or so.

I think you should start making your modifications to anonymize.py from this version: https://github.com/bastula/dicompyler/blob/4e5c570bbbf4fb26fab7afbe24d24957757711b3/dicompyler/baseplugins/anonymize.py

as that will still be compatible with the 0.4.2 binary version.

The pubsub dependency was modified in wxPython 3.0 and above so the master branch anonymize.py won't work.

Hope that helps,

Adit

Hi Aditya,

Thanks for this crucial information, it solved my problem. Didn't look into the dependencies properly apparently.

Will there be new binary versions as the current one is from 2014?

It might be interesting to modify the anonymization plugin to have users select which items they want to anonymize. If I have some spare time I will look into that.

[Aditya Panchal]

Hi Wenze,

Great to hear that it worked.

There will be new binary versions once the rest of dicompyler has been tested. As you can see the anonymize.py hasn't been updated. So I would like to work on this some more before setting up a release.

Modifying anonymize.py would be great. I think if you are able to get that going, we can include that in the next release.

Thanks!

Adit
