A DICOM Presentation State is a separate SOP instance that has instructions on how an image should be displayed (zoom, rotate, annotate, etc.). Presentation States allow images to be displayed in a certain way without changing the original DICOM image. For example, a presentation state might be used to rotate an image 90 degrees or add an arrow to an image pointing out an area of interest.
Note: CoreGateway version 1.2.250128 (rev.1076) or greater required to upload Presentation States.
Presentation States support the following:
- GraphicObjectSequence
- TextObjectSequence
- Shutter Mask
- Display Area
- WW/WC
- Spatial transformations
- Lookup Tables (LUTs)
- DICOM Overlays
Multiple presentation states can be received for one DICOM item. If multiple presentation states are received, the last received will be displayed by default. Other presentation states can be applied by clicking the three vertical dots in the top left corner of the image pane and selecting Presentation States.
Available presentation states display at the top of the list.
- Apply default: Applies the default presentation state to the selected image only. The default presentation state is defined as the last received presentation state.
- Apply default (all frames): Applies the default presentation state all images in the study.
- Clear: removes the presentation state from the selected image.
Clear (all frames) removes presentation states from all images in the study.
When viewing a cine, the scrub bar appears darker on frames that have a Presentation State applied so that a user can easily navigate to those frames.
