To better understand the perspectives, think of the data as a cube.
The B-scan viewport shows the slice data in planes parallel to the
front of the cube or the side of the cube. The X slice parallel to the
front of the image is also known as the fast B-scan because this is
the direction in which each line of A-scans is acquired extremely
quickly (in milliseconds). The Y slice parallel to the side of the cube
is also known as the slow B-scan because this scan comprises a
reformatting of vertically parallel A-scans acquired in successive line
scans. These combined lines are assembled relatively slowly, one
per line of horizontal A-scans, in comparison to the fast B-scans.
You may change between viewing the fast or slow B-scans by
toggling the Fast or Slow B-scan Display icon.
