Hi @alainmazy 

The anonymization service is perfect as now, the "standard" anonymization anonymize everything but you can play with Replace or Keep to change or avoid to erase some tags.

The question of the Study / Series date / Time is complicated, for CT/MR/US studies it is probably safe to erase them. 
For PET and NM it is forbidden because this time data are used to calculate decay correction in image processing software.

In our Anonymization tool we are building we designed scenario following the NEMA recommendation, we made a "Date" and "Body characteristic" option to keep related tag (because for PET patient wheight, height and even sex are important to calculate SUV/SUL values).

Tomorrow we have a call with Frederic to present the anonymization work we are doing using Orthanc. I will explain you our design for anonymization. 

In short, my advise is too keep your anonymization kernel as it is now : Erase every tag listed in the NEMA documentation and then the Keep and Replace option in the API will make the user able to design different level of anonymization. 

Probably the default anonymization which erase everything is too hard and will lead to loose valuable data, however your Orthanc design for anonymization "kernel" is really good. The solution might be to update OrthancExplorer to manage different option of anonymization with playing with Keep argument (we will give you our source of our anonymization software with the scenario we designed).

Best regards,

Salim
