11.2 Gain Calibration
CAUTION
Keep to the exposure interval defined in the Operation Manual of the X-ray high
voltage generator when making continuous exposures. An interval of 1 minute
or longer normally needs to be taken.
INSTRUCTION
- In the case where the machine-specific data is installed into a fresh installation of
the MC software V12.0 or later, perform the gain calibration on the CENTER panel
unit.
- In the case where the machine-specific data is installed into a fresh installation of
the MC software V11.0 or earlier, perform the gain calibration on all of the panel
units (TOP, CENTER and BOTTOM).
- In the case where the MC software is upgraded from V11.0 or earlier to V12.0
or later, the gain calibration has been performed under the MC software V11.0
or earlier. Therefore, perform the gain calibration on all of the panel units (TOP,
CENTER and BOTTOM).

NOTE
u
- Do not change the tube position in the gain calibration. If the tube position is
changed, a line defect is wrongly detected at the upper and lower ends of the
CENTER panel unit. This may cause an artifact or a defective at the boundary of the
panel unit.
- If an artifact has occurred, take the following measure.
- For TOP panel unit or BOTTOM panel unit
Perform the full calibration for the target panel unit.
- For CENTER panel unit
Perform the full calibration and marker calibration.
REFERENCE
The focal size of the X-ray high voltage generator may be either large or small.
