3-40
3.4.2 Image is Dark or Black in General (Still With Structure of the Object)
3.4.3 Image is Bright or White in General (Still With Structure of the
Object)
No. Cause Response
1 Output density in the G process
parameter is set high in general.
See the Image Process Adjustment Manual and set
the Density H/L in the G process parameter lower.
2 X-ray dosage is too much (in case of fix
the process or unprocessed image).
Confirm the exposure condition if the X-ray dosage is
not too much.
3
S value (gain) set in the REGIUS console
is too large (in case of fix
the
process or
unprocessed image).
Set the S value to the appropriate value.
4 Sensitivity calibration problem (in case of
fix the process and unprocessed image).
Redo the sensitivity calibration.
5 The ROI recognized for process was not
setup correctly for some reason.
Set the ROI to the correct position.
No. Cause Response
1 Output density in the G process
parameter is set low in general.
See the Image Process Adjustment Manual and set
the Density H/L in the G process parameter higher.
2 X-ray dosage is extremely low or not
generated at all.
• Confirm the exposure condition.Confirm that the
exposure switch is not released during the X-ray
exposure.
• Confirm the X-ray dosage using the dosimeter.
3 S value (gain) set in the REGIUS
console is too small (in case of fix the
process or unprocessed image).
Set the S value to the appropriate value.
4 The ROI recognized for process was not
setup correctly for some reason.
Set the ROI to the correct position.
5 Photomultiplier switch on the LMC is
turned OFF.
Turn it ON.
6 Problem with the LMC. Replace the LMC.
See "5.6.2 Replacing the LMC (Page 5-79)" for the
procedure to replace the LMC.
7 Failure of the photomultiplier. Replace the photo multiplier filter assy.
See "5.6.4 Replacing the Photomultiplier Tube Filter
Assy (Page 5-81)" for the procedure to replace the
photomultiplier filter or assy.
