Figure C.11.19-1. Applicable pixel shift in case of multiple pixel shift regions​

Note​

For example, the contrast frames 4 to 10 of a SOP Instance "A" are subtracted to the mask frame 1, the subtraction of the​ frames 4 to 7 being performed with three different values of mask pixel shift on overlapping rectangular regions: The​ (row,column) coordinates of the top-left and bottom-right vertices of the regions are 1: (1,1) to (30,60), 2: (10,40) to (50,120)​ and 3: (20,20) to (70,80). The mask pixel shift to be applied to the pixel (25,50) corresponds to the region 3 because this​ pixel is contained in the intersection of the three regions (see Figure C.11.19-2 and Figure C.11.19-3).​

C.11.22.2 Presentation Sequence Collection UID​

A set of Presentation States with the same value of Presentation Sequence Collection UID (0070,1102) defines a sequence of views.​
