Overview​

OmegaAI introduces a Study Locking mechanism designed to protect finalized studies from accidental or unauthorized modifications. When a study reaches a specific configurable status, the system automatically locks it. It makes it read-only across key modules — while still allowing controlled overrides for authorized users when necessary.

What's New​

1. Configurable Study Locking Trigger​

What changed​

Study locking is triggered when a study status reaches the configured threshold defined in the workflow step mapping "Prevent Modification ≥ PRIOR." Once met, the study becomes locked and read-only. The mapping between study status and the Prevent Modification workflow step is fully configurable per organization.

Benefit​

Organizations can define exactly at which status level a study becomes protected, providing flexibility to align locking behaviour with their specific clinical and operational workflows.

2. Read-only behaviour across Worklist and Study Pages​

What changed​

When a study is locked, all editable components on the Worklist page and all study fields on the Study page become read-only. For users without special permissions, edit buttons are hidden and replaced with a lock icon. Hovering over the icon displays a tooltip indicating the study is locked and cannot be modified.

Benefit​

Prevents accidental edits to finalized studies and provides clear visual feedback to users about the locked state, reducing confusion and errors.

3. Modify Locked Study — new UAC privilege​

What changed​

A new User Access Control (UAC) privilege, "Modify Locked Study," has been introduced. Users assigned this privilege (e.g. QA personnel, lead technologists) can see the Edit button on locked studies. When saving changes, a confirmation dialog is displayed requiring explicit confirmation before changes are applied.

Benefit​

Enables controlled overrides for authorized users without compromising the integrity protections applied to all other users, supporting both compliance and operational flexibility.

4. Image ingestion supported for Locked Studies​

What changed​

OmegaAI can continue to receive and ingest new DICOM images into locked studies through all ingestion paths, including standard image routing workflows. Image and series counts are automatically updated upon ingestion. However, protected metadata — including patient information, study descriptions, and order details — remains unchanged.

Benefit​

Ensures critical imaging operations are not blocked by locking, while still safeguarding finalized study metadata from being overwritten or altered unintentionally.

5. Audit logging for locking activity​

What changed​

OmegaAI now logs all activities related to study locking, including configuration changes, successful image ingestion into locked studies, privileged user overrides, and blocked modification attempts by unauthorized users.

Benefit​

Provides a complete audit trail for compliance, traceability, and regulatory requirements, ensuring full operational transparency around finalized imaging studies.

Watch It in Action​

Important Notes​

• Locked studies are read-only for all users without the "Modify Locked Study" UAC privilege — edit buttons are hidden on the study information page.
• The locking threshold is configurable per organization via the workflow step mapping; changes to this configuration are audit-logged.
• Image ingestion into locked studies is permitted, but protected metadata fields cannot be overwritten during ingestion.
• Users with the "Modify Locked Study" privilege must explicitly confirm the intent to modify via the system confirmation dialog before changes are saved.
• Study locking applies across the Worklist and Study pages; ensure all relevant user roles are reviewed and updated with appropriate UAC privileges post-release.
