8.18.3. LIH NOISE (LAST IMAGE HOLD NOISE)
The LIH Noise reduction function reduces noise in the image when the radiation switch

and cannot be used to change a previously stored image.
The system may be configured to apply low noise reduction for live images and a highe
level of noise reduction when the foot switch is released.
