16.1.1 Main Scan Position (Pixel) Adjustment
1.

with the tungsten X-ray tube at about 1 mR.
u
INSTRUCTION
u
At least two IPs should be exposed for checks before and after the adjustment.

{MC:20.2 _Image/Conveyance Checks}
3.
Measure a misalignment of the reading start position.
Measure the size of the white blank portion, and calculate an adjustment value in
accordance with the formula shown below.
--- Example ---
If the positional misalignment is 1 mm when an IP of 14"x14" (35cm x 35cm) size
is outputted to a 14" x17" (35cm x 43cm) film:
(1/1 x 10) = 10 (PIXEL)
Thus, "Input range" is +10.
4.
Enter the reading start position (e.g., “10”) calculated at step 3.
u
NOTES
u
- After entering the reading start position, do not turn OFF the power of the RU.
If the RU is powered OFF, the reading start position data will not be retained.
- “Input range” only accepts values ranging from -999 to 999.
REFERENCE
The white blank portion of the output image expands when a negative quantity (-)
value is entered, while it narrows when a positive quantity (+) value is entered.
