It should be possible to mark plans prepared to define those verification procedures in the DICOM protocol. There already exists a well-suited tag to support it, which is (300A,000A) “Treatment Intent”. The list of defined terms should be extended by “VERIFICATION”. To know which plan is verified by the current plan, the attribute RT Plan Relationship (300A,0055) should be extended with a new defined term ‘VERIFIED PLAN’, which allows specification of this relationship.</p><p>Sections of document affected:</p><p>Part 3 (Information Object Definitions), Section C.8.8.9</p><p>Correction Wording: In DICOM Part 3, Table C.8-41 (RT General Plan Module Attributes), modify the following attributes:</p><p>>Treatment Intent (300A,000A) 3 Intent of this course of treatment.
