CAUTION Ensure no detector is in X-Ray path
Follow this process to warm up the tube.
CAUTION X-rays are generated during tube warm up. Use proper radiation practices at all
times.
1. Check the room to make sure it is clear of other personnel before making X-ray exposures.
2. Click [WARM TUBE] on the Worklist screen.
Note: Because the tube warming procedure produces x-rays, it cannot be performed when an exam is
open. If the tube must be warmed before the exam can begin, suspend the exam and remove the
patient and any others from the room before warming the tube. Refer to Chapter 10: Image
Acquisition-End Exam (p. 10-31) for more information.
3. Correct any exposure holds.
CAUTION Exposures should not be made on any detector during tube warm-up. The system
will attempt to mis-align the tube and the detector, but you may need to manually
move the tube so that the detector is not exposed during the warm-up sequence.
Pay close attention to system message information for instructions to manually
move the detector. Exposing the detector may cause a “burned in” image artifact.
