Autopilot Calibrate

Run Dunkelkorrektur (dark correction)

• Captures reference images with no X-ray (tube off):

  curl -X POST http://localhost:4802/calibrate/dark-correction
  

• Wait for completion (typically 30-60 seconds)
• Verify dark reference was saved:

  curl -s http://localhost:4802/calibrate/status
  

Activate tube for bright correction

• Turn on the X-ray tube at a safe low power:

  curl -X POST http://localhost:4802/calibrate/tube-on \
    -H "Content-Type: application/json" \
    -d '{"voltage": 100, "current": 100}'
  

• Wait for tube warmup (status changes from "warming" to "ready")

Run Hellkorrektur (bright correction)

• Captures reference images with X-ray active (no part in beam):

  curl -X POST http://localhost:4802/calibrate/bright-correction
  

• IMPORTANT: Ensure no part is placed in the CT scanner during bright correction

Tune voltage and ampere

• Adjust to target voltage and current for the planned scan:

  curl -X POST http://localhost:4802/calibrate/tune \
    -H "Content-Type: application/json" \
    -d '{"targetVoltage": <kV>, "targetCurrent": <uA>}'
  

• The API ramps voltage/current gradually to avoid tube stress

Check Bilddynamik

• Read the current image dynamics value:

  curl -s http://localhost:4802/calibrate/dynamics
  

• Expected: value between 20 and 220
• If too low (<20): Increase voltage or current, or increase integration time
• If too high (>220): Decrease voltage or current, or decrease integration time
• Adjust and re-check:

  curl -X POST http://localhost:4802/calibrate/adjust-dynamics \
    -H "Content-Type: application/json" \
    -d '{"integrationTime": <ms>}'
  

Run rotation preview

• Verify the part is centered and dynamics stay in range through full rotation:

  curl -X POST http://localhost:4802/calibrate/rotation-preview
  

• Reports min/max dynamics across all rotation angles
• If any angle is out of range, suggests repositioning the part

Save calibration profile

• Store the calibrated settings for reuse:

  curl -X POST http://localhost:4802/calibrate/save \
    -H "Content-Type: application/json" \
    -d '{"profileName": "<part-type>-<date>"}'
