Managing Phased Array Image Display 267
In A/S Vert and A/S Horz, the x-axis grid modes of the A-scan and S-scan are directly
correspondent to each other.
For example, in A/S Vert screen mode with the Standard x-axis grid pattern active,
the horizontally oriented A-scan grids from 0 to 10 connect with the grids on the
S-scan. These horizontal lines allow you to visually correlate an A-scan indication at
division 3 with its corresponding S-scan image, also at division 3.

The A-scan display is a sound path A-scan. Therefore, indications on the A-scan
do not line up horizontally with their corresponding indications on the S-scan.
This requires that the grids applied to the S-scan are curved to follow a sound
path contour (see Figure 14-10 on page 267).
