DICOM resources

DICOM images can be uploaded to the resource library and then added to an item for use in an exam. During an exam the candidate will be able to interact with the DICOM resource, viewing each individual image in order to answer questions.

Only specific DICOM formats and TransferSyntax are supported, use the guide below to ensure your resources are formatted correctly.

DICOM image support
