Patient Image Analysis
Image Enhancement Gammas
Linear
The Linear gamma represents a "standard" processing
algorithm. Linear describes a greyscale representation
of a B-Scan Plus echogram in which the brightness
represented on the screen is directly proportional to the
strength of the ultrasonic echo. Therefore an ophthalmic
structure which reflects the maximum echo would be
represented as pure white, while no echo would be
represented as pure black; and echoes in between
would be represented proportionally as shades of gray,
directly proportional to the strength of the ultrasonic
echo. Figure 119 below displays an example of a B-
Scan Plus image with a Linear Full Range gamma
setting.
