Z.2.5 Precautions for Urgent Use
When you start a study before completion of the calibration at the time of startup, the operation will
be in Urgent Use Mode. At this time, “Urgent use is possible” appears in the “Output Device Status
window” of the image processing unit.
• There is no guarantee that the image taken in Urgent Use Mode can be used for diagnostic
purposes. Vertical artifact could appear in the image, if the temperature difference is large from
the previous shutdown of the system. Check the image quality before use.
• Move from the Study Screen to the Patient Information Input Screen immediately after exiting
Urgent Use Mode, so that the calibration will start over automatically.
Z.2.6 Precautions Related to Continuous Operation
If you plan to continuously run the system for over 24 hours, perform post-operation check, and
then restart the system.
Otherwise, calibration will not be performed normally, and image quality cannot be guaranteed as a
result.
Z.2.7 Precautions Related to Grid
Depending on the type of the grid used, its stripes may appear in the image after making an
exposure. To avoid such moire effects, sway the grid from side to side, or use the Grid Pattern
Removal Processing Software in conjunction with the grid with 40 lines.
Z.2.8 Precautions during Calibration
Observe the following when the READY status lamp on the flat panel sensor is blinking or when the
message “Calibrating...” is displayed on the image processing unit.
• Do not subject the flat panel sensor to shock.
• Do not deliver radiation.
• Do not connect/disconnect the flat panel sensor to/from the power supply unit or power box.
Z.2.9 Precautions for Exposing the Flat Panel Sensor to X-ray
When you expose the flat panel sensor to X-ray at any other time except during radiography,
artifacts could appear in the image. If artifacts appeared in the image due to X-ray irradiation,
perform a test X-ray radiography after waiting for more than 2 minutes and then restart exposure
after confirming that the artifacts disappear.
Z.2.10 Precautions for Extended Image Readout
If any impact is applied to the flat panel sensor while an image is being acquired with Extended
Image Readout, artifacts may appear in the image. Before removing the flat panel sensor from the
radiographic examination stand, be sure to check the acquired image on the image processing unit.
In addition, note that when Extended Image Readout is enabled, the system cannot be used in an
emergency since the system start-up time becomes longer.
