Figure 10-27 Using the AREA parameter in TE
The combined AREA parameters for the over and under-penetrated regions cannot be greater than
100%. For example if the AREA parameter for over-penetrated regions is set to 40%, the AREA parameter
for under-penetrated regions cannot be greater than 60% (100-40).
Strength
The STRENGTH parameter affects the grayness of a region when TE is applied to it. For example,
increasing STRENGTH for under-penetrated regions such as shoulders makes a white region grayer.
Increasing STRENGTH for over-penetrated regions such as lungs makes a black region grayer. In both
cases, increasing STRENGTH generally makes the region grayer.
The effect of varying AREA and STRENGTH in TE is demonstrated in Figure 10-28 for under-penetrated
regions. Increasing STRENGTH while keeping the AREA constant makes the pixel grayer in the shoulder
region. Increasing AREA extends the region that becomes gray.
