A medical imaging system includes a data store having stored medical imaging data and a computer. The system may be in a medical treatment room and is adapted to receive and display imaging data from a medical procedure. The computer has a graphical user interface that receives authentication credentials. An authenticator alternately prevents or allows a user access by logging the user into the system using the authentication credentials. A file accessor receives received medical imaging data and stores it in the data store, and retrieves the stored medical imaging data and provides it to the graphical user interface for display. Documentation data is received through the graphical user interface and is stored in the data store without requiring the user to provide the authentication credentials or be logged into the system. The user cannot access the stored medical imaging data before providing the authentication credentials and being logged into the system.
