Viewing and editing individual x-ray system display names and set user defined modality using the web interface¶
New in 0.7.0
Functionality changed in 0.8.0
Previous versions of OpenREM used each x-ray system’s DICOM
station name as
the identifier for each x-ray system. The front page showed a summary of the
number of studies for each unique
station name stored in the system.
This led to a problem if multiple x-ray systems used the same station name: the
OpenREM home page would only show one station name entry for these systems,
with the number of studies corresponding to the total from all the rooms. The
name shown alongside the total was that of the system that had most recently
sent data to the system.
This issue has been resolved by introducing a new field called
display name. This is unique to each piece of x-ray equipment, based on the
combination of the following eight fields:
- institution name
- station name
- department name
- model name
- device serial number
- software version
- gantry id
The default text for
display name is set to a combination of
institution name and
OpenREM determines the modality type of a system based on the information in the DICOM dose structured report . However sometimes this mechanism failes because vendors use templates meant for RF also for DX systems. Therefore it is possible from version 0.8.0 to set a modality type for each system manually. A manually set modality type overrides the automatically determined value.
If you log in as a normal user then the
Config menu becomes available
at the right-hand end of the navigation bar at the top of the screen.
The third option,
View display names & modality, takes you to a page where
you can view the list of x-ray systems with data in OpenREM together with their
current display name and user defined modality. If the user defined modality
is not set, the value contains
None. The x-ray systems are grouped
into modalities and displayed in five tables: CT; mammography; DX and CR;
fluoroscopy; and other.
If you wish to make changes to a display name or to the user defined
modality then you must log in as a user that is in the
admingroup. You will
then be able to use the
Display names & modality item under the
This will take you to a page where you can view the list of x-ray systems with
data in OpenREM. If you wish to change a display name or the user defined modality
then click on the corresponding row. The resulting page will allow you to
edit these parameters. Click on the
Update button to confirm your changes:
You can change multiple rows at once. For display names you may wish to do this if a system has a software upgrade, for example, as this will generate a new default display name for studies carried out after the software upgrade has taken place. The studies from these will be grouped together as a single entry on the OpenREM homepage and individual modality pages.
If you update the user defined modality, the modality type for already imported studies will also be set to the user defined modality type. Only changes from modality DX (planar X-ray) to RF (fluoroscopy) and vice versa are possible.
