What is the best value representation for boolean in DICOM?

Question

AFAIK there is no logical representation of the value, and I need to specify the logical value true / false in the private tag.

I was thinking about SH (SHort string), saying TRUE or FALSE . Is there a standard or widely used way to define it?

Answer 1

You can use encoded string (CS) VR with TRUE and FALSE as encoded values. This is done in the standard for the Time of Flight Information Used (0018, 9755) element in the advanced PET data acquisition module.
