Make use of DateTime consistent in concept names Status March 2016 Voting Packet Date of Last Update 2016/01/19 Person Assigned David Clunie Submitter Name Jörg Riesmeier Submission Date 2015/08/24 Correction Number CP-1545 Log Summary: Make use of DateTime consistent in concept names Name of Standard PS3.16 Rationale for Correction: In PS3.3 an effort has been made to consistently use the words "DateTime" (without a space) for all DT VR Attributes. In PS3.16 there is both inconsistency in different concepts with respect to whether DateTime or just Time is used, and worse, some concepts use different names in different templates and references and definitions. [Ed.Note: The many correct uses of DateTime in templates and definitions are not reproduced for reference here to keep the length of the CP tractable, but see, e.g., TIDs 3010, most of TIDs 37xx, 38xx, etc. Note that some special cases are not modified, e.g., TID 3301 (122701, DCM, "Procedure Time Base"), TID 10011 (113809, DCM, "Start of X-Ray Irradiation").] [Ed.Note: The change has been made not only to DCM codes, but other coding scheme code meanings, including those from SNOMED. Ideally these (and other code meanings in DICOM that are not already in SNOMED as synonyms) should be propagated back into SNOMED] Correction Wording:

Amend DICOM PS3.16 as follows:
