Calibration
6. At the top of the Dap Calibration Window, ensure that the proper Image Intensifier Size, and the proper number of Collimator
Leafs, for the system under test, are set.
7. Manually adjust the technique to 40 kVp and 5 mA. While taking an X-ray, for approximately 10 seconds, read the dosimeter
and record the Dose Rate in mR/sec.
8. Divide the Dose Rate you recorded in step 7 by 5 and enter the number into the corresponding KVp Field in the DAP
Calibration Window. Record the Dose Rate in mR/second.
9. Manually adjust the technique to 50 kVp and 5 mA. While taking an X-ray, for approximately 10 seconds, read the dosimeter
and record the Dose Rate in mR/sec.
10. Record the Dose Rate in mR/second and mA in the DAP Tube Calibration Grid.
11. Manually adjust the technique to 60 kVp and 4 mA. While taking an X-ray, for approximately 10 seconds, read the dosimeter
and record the Dose Rate in mR/sec.
12. Record the Dose Rate in mR/second and mA in the DAP Tube Calibration Grid.
13. Manually adjust the technique to 80 kVp and 3 mA. While taking an X-ray, for approximately 10 seconds, read the dosimeter
and record the Dose Rate in mR/sec.
14. Divide the Dose Rate you recorded in step 13 by 3 and enter the number into the corresponding KVp Field in the DAP
Calibration Window. Record the Dose Rate in mR/second.
15. Manually adjust the technique to 100 kVp and 2 mA. While taking an X-ray, for approximately 10 seconds, read the
dosimeter and record the Dose Rate in mR/sec.
16. Divide the Dose Rate you recorded in step 15 by 2 and enter the number into the corresponding KVp Field in the DAP
Calibration Window. Record the Dose Rate in mR/second.
17. Manually adjust the technique to 120 kVp and 2 mA. While taking an X-ray, for approximately 10 seconds, read the
dosimeter and record the Dose Rate in mR/sec.
18. Divide the Dose Rate you recorded in step 17 by 2 and enter the number into the corresponding KVp Field in the DAP
Calibration Window. Record the Dose Rate in mR/second.
19. Point and click on the Calculate Coefficients Button.
20. In the upper left-hand corner of the RUT Main Menu, point and click on FILE .
