4. QA Parameters
When MLT(F) frequency processing is selected, the QA parameters (%IP_PARAM%) in Anno-
tation are displayed in the format below.
n stands for the numeric value, character or symbol displayed on Annotation.
1 REX
The parameter is displayed as follows:
REXn
If LUT is set to REX ADJUST for x-ray exposure, F-REX is displayed.
2 Frequency Processing Mode
If MLT (F) FREQUENCY is selected as the Frequency Processing Mode, Q1 is
displayed. Q0 is displayed for STD. FREQUENCY, and Q2 displayed for MLT (M)
FREQUENCY. For other QA parameters displayed when the mode other than MLT
(F) Frequency Processing is selected, please refer to the respective manuals.
3 DWT Edge Enhancement
The parameters are displayed as follows:
En (EFFECT) n (FREQUENCY BASE, represented with the alphabet on the
button) n (DENSITY BASE, represented with the alphabet on the button)
If the DWT Edge Enhancement is not effective, nothing is displayed.
The display values correspond to the actual values as shown in the following table:
Effect
4 DWT DEP
The parameters are displayed as follows:
Dn (STARTING DENSITY of High-Density Field), n (DEP WEIGHT of High-
Density Field), n (DEP EFFECT of High-Density Field), n (STARTING
DENSITY of Low-Density Field), n (DEP WEIGHT of Low-Density Field), n
(DEP EFFECT of Low-Density Field)
If the DWT DEP is not effective, nothing is displayed.
If only the High-Density Field is not effective, * is displayed instead of the
parameters (D*, 10, 10, 10), and if only the Low-Density Field is not effective, * is
displayed instead of the parameters (D25, 10, 10, *).
The display values correspond to the actual values as shown in the following tables
(the values for DEP EFFECT are omitted):
