How to Redact DICOM Files in VIDIZMO

VIDIZMO detects and redacts protected health information (PHI) in DICOM medical images — both the patient details in the header tags and any text burned into the image. This guide covers uploading a DICOM file, running redaction through the VIDIZMO Indexer, and retrieving the redacted copy.

To learn what gets detected and removed, see Understanding DICOM Processing in VIDIZMO.

Prerequisites​

  • Belong to a group with the Redaction feature, or have a CAL that grants it.
  • Have the Document feature enabled to upload DICOM files.
  • Configure the VIDIZMO Indexer for PII detection and OCR.
  • To scan header tags with AI for additional PII, turn on Enable AI Metadata Redaction in the VIDIZMO Indexer's PII detection and redaction settings.

For configuration guidance, see Configuring VIDIZMO Indexer for PII Detection and Redaction.

Upload a DICOM File​

  1. In the Library, upload your DICOM file. VIDIZMO recognizes the .dcm, .dicom, .dic, and .ima extensions.
  2. If your file came from a medical system without an extension, upload it as is — VIDIZMO identifies it as DICOM from the file's signature.

Note: DICOM files don't have an in-browser preview. After upload, the file appears in the Library as a downloadable medical file.

Automatic Processing​

When automatic processing is turned on in the VIDIZMO Indexer:

  1. Upload the DICOM file to the Library.
  2. VIDIZMO processes it for the configured AI insights (PII and OCR text).
  3. Once processing completes, a redacted copy appears in the Library.

On-Demand Processing​

To redact a DICOM file manually:

  1. In the Library, select the file's overflow menu (three dots).
  2. Select Process.
  3. In the Process modal, select Generate AI Insights.
  4. Select the AI insights to detect:
    • PII for patient names, identifiers, and other personal data
    • OCR for text burned into the image
  5. Select the Redaction Classes for each insight.
  6. Set the Confidence Threshold if required.
  7. Select the Action for the original file.
  8. Select Start to begin redaction.

Once processing completes, a redacted DICOM file is created and stored in the Library.

Note: VIDIZMO redacts a standard set of identifying header tags by default. To also scan the header tags with AI for additional PII, turn on Enable AI Metadata Redaction in the VIDIZMO Indexer before processing.

Process Multiple Files at Once​

To redact several DICOM files together:

  1. In the Library, select the files using the checkboxes.
  2. On the ribbon, select Process.
  3. Configure the AI insights and redaction options as described above.
  4. Select Start to process all selected files.

Download and Verify the Redacted File​

Because DICOM files have no preview, download the redacted copy from the Library and open it in a DICOM viewer to confirm that the burned-in text and header tags are removed. The redacted file remains a valid DICOM and opens in standard viewers.
