What's the best value representation for boolean in DICOM?

Question

AFAIK there's no boolean value representation, and I need to specify a boolean true/false in a private tag.

I thought of a SH (SHort string), saying TRUE or FALSE. Is there a standard or widely used way to specify it?

Answer 1

You can use a Coded String (CS) VR with TRUE and FALSE as coded values. This is done in the standard for the Time of Flight Information Used element (0018, 9755) in the enhanced PET acquisition module.
