4. Analysis of Abnormal Images
u
INSTRUCTION
u
If you contact TIMS to proceed the abnormal image analysis efficiently, provide the
following information.
In addition, depending upon the analysis results, both types of SEs the GOS and Csl
might need to be calibrated.
- The CL screen capture of the abnormal image as a JPEG image
- Writting of arrow and malfunction details (white streak, black streak, horizontal
streak, vertical streak, gradation, etc.) on the aforementioned abnormal spot
- Image data files for 3 images each for before and after the abnormal image occurred
that have been saved in the "C:\Program Files \Fujifilm\IIP\Data\Image" of the CL,
apart from the individual information file (*.inf)
- Calibration data of the current panel and other registered panels, and the number of
the current panel from "Back up Correct ALL Data" of PC-TOOL
- Log data from "Back up Correct ALL LOG" of PC-TOOL
Open "IMO.LOG", "OPER.LOG" or "ISC.LOG" with Notepad and confirm that the
time before and after the abnormal image occurred is included in the log. As the
result of confirmation, if the time has not been updated, restart the CL and reacquire
the log data.
- Hearing about when the abnormal image occurred
Perform the hearing on the following items in the possible range.
- Exposure condition (region, kV, mAs, SID, etc.), irradiation field focusing and
added filter when the abnormal image was exposed.
- Exposure environment (ambient temperature, total image count of the day,
X-ray equipment manufacturer, if the equipment have been operated for
24 consecutive hours or not, specification of the grid being used, exposure
workflow, etc.)
- If abnormal images occurred repeatedly
4.1 Analyzing Moiré
When the movable grid is used, the moiré might occur due to X-ray irradiation time or
the grid drive timing.

START
Is the X-ray irradiation time 10 msec or
longer?
YES
NO
Change the X-ray irradiation time to 10 msec or longer
and make exposues.
Does the moiré occur again on the image?
YES NO
END
The grid drive timing might be off.
Report the situations to the service personnel of the X-ray equipment to
have timing delay adjusted by means of the exposure stand trimmer
Is the image is normal recorded after the adjustment?
(Is the image free from the moiré?)
YES
NO
