Process of comments ? How to know if there is a document for public comment?
Usually this information is distributed through the Mailing list of the responsible Domain Technical Committee.
You can also find this information on the IHE International Website where you can download the latest version and get information on the documents current status.

Comments should in general be sent to the address given in the document asking for comments.
Another possibility is the IHE Forum on the RSNA website for discussions as well as submitting and reviewing comments: http://forums.rsna.org/
