|Attribute Name||Tag||Type||Attribute Description|
|Mask Subtraction Sequence||(0028,6100)||1C||Required if Mask Module is present. Only a single Item shall be included in this sequence. Applicable Frame Range (0028,6102) shall not be included in the Sequence Item. See C.7.6.10 for a complete definition of the Attributes in the Items of this Sequence other than Mask Operation(0028,6101) and Applicable Frame Range (0028,6102). Notes: 1. This Sequence is replicated here in order to specify one Item, additional conditions on Mask Operation (0028,6101) and to forbid Applicable Frame Range (0028,6102). 2. The role of Applicable Frame Range (0028,6102) is replaced by Referenced Frame Number (0008,1160).|
|>Mask Operation||(0028,6101)||1||Type of mask operation to be performed Enumerated Values: AVG_SUB TID See C.184.108.40.206 for further explanation. Note: The requirement in this module is for Enumerated Values which override the requirements of the Mask Module.|
