Dynamic Range
Gray Scale Mapping (Gray Map)
Description
Controls how echo intensities are
converted to shades of gray.
Determines how the echo intensity levels
received are presented as shades of gray.
Benefits
Useful for optimizing tissue texture to
differentiate between echo levels that are
close together.
Dynamic range should be adjusted so that
the highest amplitude edges appear as
white while lowest levels (such as blood)
are just visible.
Displays the received echo levels with
different weights on specific levels of gray.
For example, a certain gray map may
enhance mid level echoes over a wider
range of grays verses high or low level
echoes.
Allows for better differentiation between
echo levels through gray levels displayed.
Values
The settings cycle in 6 dB steps from
30 dB to 90 dB. Use presets to set the
output preferred to any scan mode and
exam combination. The default for B
Dynamic Range is set in the Set
Up/Custom Display menu page 2.
Dynamic range levels are returned to the
preset value when changing the following:
