In order to
view the slice below the open slice and detect
misalignments, change the level of transparency operating the
transparency bar from the Toolbar. As shown in
Figure 1, the transparency bar appears on the right of the Toolbar when the
Slice Alignment Tool
Transparency bar appears on the right of the Toolbar.
transparency ranges from 0% (the knob on left extreme) which means that the
slice is completely opaque, to 100%
(knob on the right extreme) which means that the slice is completely
transparent. An intermediate value is obviously the best way to visualize
both slices as shown in Figure 2.
Use of transparency bar for visualizing consecutive slices simultaneously.
All registration operations such as translation and rotation of slices can be
performed with any level of transparency.
Show contours of objects
that span both slices and make the slice completely transparent. There appears
the contours of the open slice drawn over the slice below it, which may be very
helpful for detecting misalignments. See Figure 3.
