You can use this feature to add pixel-level annotations on DICOM.
Annotating a Dataset in Your Workgroup
To annotate a dataset from your workgroup, complete the following steps.
- Open the integrated OHIF DICOM viewer from the tabular viewer by selecting your dataset of interest in the datasets view.
- Select the Data tab, then click the DICOM UID for your study, series, or instance of interest.
- The Open Health Imaging Foundation DICOM Image viewer appears.
Annotating a Dataset from a Different Workgroup
To annotate a dataset from a different workgroup, complete the following steps.
- Open the tabular viewer by selecting the relevant Secure Access List.
- Select the DICOM UID for your study, series, or instance of interest.
3. The Open Health Imaging Foundation DICOM Image viewer appears.
Adding Pixel-Level annotation
DICOM visualization and annotation via the Rhino FCP is facilitated by an integrated version of the Open Health Imaging Foundation (OHIF) viewer, which comes equipped with standard tooling for visualization and manipulation of DICOM images.
The following annotation types supported:
- Rectangle
- Line/Length
- Arrow
- Angle
- Ellipse
To add a pixel-level annotation to a DICOM file, open the file using the OHIF viewer, select your preferred annotation, and create your annotation on the image. To save the annotation(s), click on Measurements -> Save measurements.
NOTE: Saving an annotation on the OHIF viewer will create a new DICOM SR file which references the original DICOM file and produce a new Dataset version. When this happens, the platform will automatically make all previous versions inactive (and invisible to the user) except the original V.0 and any other version that is already associated with a specific Code Run.
For more information on how to use the viewer, see the Open Health Imaging Foundation Viewer Guide: https://docs.ohif.org/user-guide/viewer/.
