1. Workstation receives “Acquire” request, send command “Clear” to detector.
2. Detector receives “clear” from workstation and begins flushing panel. Meanwhile,
replies to workstation “Exposure Prohibited”.
3. Detector finishes “Clear” and sends message “Exposure Enable”
4. “Exposure Enable” is shown on iDetector’s bar, user takes X-ray.
5. User triggers X-ray generator to initialize and do anode rotation to prepare for X-ray.
6. X-ray generator finishes preparation and replies to user
7. X-ray generator begins releasing X-ray
8. X-ray generator finishes taking X-rays.
9. Workstation prepares receiving image.
10. Detector begins data acquisition after time limits.
11. Detector completes image acquisition and begins image transmission.
12. Workstation receives all images.
Images received will be preview images; preview images are those without much correction which
causes some stripes; they cannot be used for final diagnosis.
The detector will make another dark image acquisition for offset correction. If Hardware Post offset
and Hardware calibration are selected, the detector uploads the processed image to the
workstation after offset, gain and defect calibration.
If Software Post offset and Software calibration are selected, the corrected image is shown on
the screen after the workstation finishes offset, gain and defect calibration.
Note: If the wireless condition is bad, the detector cannot send even one package in 30s. It will
stop trying to send image packages. Users have to retrieve images from the detector when the
wireless condition is good enough.
