5 DWT Noise Reduction
The parameters are displayed as follows:
Nn (EFFECT), n (PROCESSING UPPER LIMIT)
If the DWT Noise Reduction is not effective, nothing is displayed.
6 LUT Parameters
The parameters are displayed as follows:
Gn (CURVE SHAPE) n (BRIGHTNESS), n (CONTRAST)
The Curve Shapes are represented by the following symbols respectively:
CS: CHEST, SS: STAN. CONTRAST, LI: LINEAR, IL: INV. LINEAR,
BS: BONE #1, GS: BONE #2
The display values correspond to the actual values as shown in the following table
(the values for CONTRAST are omitted):
BRIGHTNESS
