I got a call the other day from a practice in Nevada.  The doctor described a Metron issue.   A visiting regulatory compliance examiner identified an issue that they stated "requires remediation". The examiner noted that in Metron the anatomy annotations can be changed long after the image acquisition and then made it clear that this is a regulatory violation.   

Quickly solved - within Metron we have the option to turn on a "user login" prompt.  By defining specific users and their roles we can then turn on and off specific features. In this case we turned off the option to change anatomy annotations after the images have been "accepted".  We also have an activity log that even presents the "attempt" to change the annotations and who made that attempt.  Similarly we have made it easy to track who has deleted, copied, move, and many other actions.   This detail will be useful to help satisfy most any regulatory compliance requirements.
