Converting segmented lamina cribrosa from embedded to FoBMO orientation and from left to right eye configuration. Left: The FoBMO vertical axis is established relative to the embedded tissue vertical as depicted for a right eye (OD) in Figure 2. Middle: The embedded data set is rotated (in this eye, counterclockwise 19.8°) to bring the FoBMO vertical optic nerve head anatomy into the vertical coordinate position. Right: FoBMO-oriented left eye (OS) data are translated to FoBMO right eye configuration, by shifting the x-axis location of each voxel to a position that is equal in distance to but opposite in direction from the y- (FoBMO vertical) axis while holding the y- and z-axis positions (not shown) constant. The position of a representative group of surface voxels is shown through each step of the process by a green dot.
