MASK MODULE ATTRIBUTES (C.7-16)


Tag Attribute Type Description
(0028,6100)Mask Subtraction Sequence1 Defines a sequence that describes mask subtraction operations for a Multi-frame Image.
(0028,6101)>Mask Operation1 Defined Term identifying the type of mask operation to be performed. See C.7.6.10.1 for further explanation.
(0028,6102)>Applicable Frame Range3 Each pair of numbers in this multi-valued attribute specify a beginning and ending frame number inclusive of a range where this particular mask operation is valid. Discontinuous ranges are represented by multiple pairs of numbers. Frames in a Multi-frame Image are specified by sequentially increasing number values beginning with 1. If this Attribute is missing in this particular sequence item, then the mask operation is applicable throughout the entire Multi-frame Image, subject to certain limits as described in C.7.6.10.1.1.
(0028,6110)>Mask Frame Numbers1C Specifies the frame numbers of the pixel data used to generate this mask. Frames in a Multi-frame Image are specified by sequentially increasing number values beginning with 1. Required if the Mask Operation (0028,6101) is AVG_SUB.
(0028,6112)>Contrast Frame Averaging3 Specifies the number of contrast frames to average together before performing the mask operation. If the Attribute is missing, no averaging is performed.
(0028,6114)>Mask Sub-pixel Shift3 A pair of floating point numbers specifying the fractional vertical [adjacent row spacing] and horizontal [adjacent column spacing] pixel shift applied to the mask before subtracting it from the contrast frame. See Section C.7.6.10.1.2.
(0028,6120)>TID Offset2C Specifies the offset to be subtracted from the current frame number in order to locate the mask frame in TID mode. If zero length, TID Offset defaults to 1. Required if Mask Operation (0028,6101) is TID.
(0028,6190)>Mask Operation Explanation3 Free form explanation of this particular mask operation.
(0028,1090)Recommended Viewing Mode2 Specifies the recommended viewing protocol(s). Defined terms: SUB = for subtraction with mask images; NAT = native viewing of image as sent. Note: If an implementation does not recognize the defined term for Recommended Viewing Mode (0028,1090) , reverting to native display mode is recommended.
