DICOM Anonymizer FAQ
Is this DICOM anonymizer free?
Yes. Anonymize as many files as you like, with no account and no limits beyond your device's memory.
Are my files uploaded?
No. The files are read and rewritten in your browser and never leave your device.
What is removed?
Attributes listed in the DICOM PS3.15 Basic Application Level Confidentiality Profile: patient name, ID and birth date, other IDs, accession number, physicians, operators, institution and device details, descriptions, comments, dates and times, and all private tags. UIDs are replaced with new ones, the same way in every file, so studies and series stay linked.
Can I keep some information?
Yes. You can shift dates by a number of days instead of removing them, keep age, sex, size and weight, keep study and series descriptions, device or institution details, or the original UIDs. The output records which options were used.
Is the image changed?
No. Pixel data is copied unchanged and the files keep their compression. Text burned into the pixels is not removed, so check ultrasound and screen captures before sharing.
