Audit log: review all events, recorded for Source/Material/Aliquot/Test
Do you know that for security reasons each object tracking form in PACS includes Audit log tab, which displays all events, recorded for an object, user performed an operation, and timestamps?
It can be used in situations when incorrect data is shown on a tracking form, to review who entered or changed the data, when it was done, what was the previous old value for this field, and to take necessary actions.
