[Troubleshooting when abnormal images occur]
(1) Execute the log gathering tool.
(2) Check the calibration images (White*.dcm) on the monitor.
(3) Conduct the self-diagnosis test, and check the test results. (Calibration must not be
performed.)
(4) Check whether the abnormal images recur.
· If the problem occurs with a high frequency: Proceed with X-ray exposure, obtain five
abnormal images, and proceed to step (5).
· If the problem occurs with a low frequency: Obtain at least one abnormal image, and
proceed to step (5).
Note: When the problem occurs with a low frequency, X-ray exposure can be continued,
but the effects of the heat may cause the X-ray tube to deteriorate so a waiting
period must be provided during continuous exposure and the exposure undertaken
while at the same time cooling down the X-ray tube.
(5) Replace the sensor cable (at power box side).
(6) Replace the power box.
(7) Replace the sensor cable (at imaging unit side).
The sensor cable (at imaging unit side) must be replaced only by a service technician who has
completed the service training.
Steps (6) and (7) must be performed by the service technician who has been dispatched to the
customer's site.
If the abnormal images recur after the steps outlined above have been taken, the imaging unit
must be returned to the office of the distributor (agent).
The secondary-level response steps are then undertaken.
Even when the problem occurs with a low frequency, at least one abnormal image must be
obtained.
* When a secondary-level response is requested, the following information must be provided
without fail:
· Details of how the system has been operated on-site (system configuration, optional
software, etc.)
· CXDI software version
· Shock sensor statuses
· All the images described as abnormal by the user as well as the images (2 or 3 of them)
taken immediately before and immediately after each abnormal image
· Abnormal images (1 to 5 of them) obtained by replication exposure
· Files saved using the log gathering tool
· Frequency with which the problem occurs
