  • [Objective] To optimize intraoperative parameters of C-arm X-ray apparatus and to effectively reduce radiation exposures to operators and patients.

    [Methods] In human model stimulation surgery, parameters of dose area product (DAP) of 5 built-in fixed programs (P1-P5) were compared under continuous fluoroscopy, pulsed fluoroscopy and high contrast fluoroscopy modes. Pelvis (P2) image qualities in pulsed fluoroscopy and high-contrast perspective modes were evaluated in accordance with the image quality standards by Commission of the European Community (CEC).

    [Results] There were significant differences in the DAP values of the same program among three modes (P<0.01). The DAP values were lower in the pulsed fluoroscopy mode than in the continuous fluoroscopy mode and the high contrast fluoroscopy mode (P<0.01). There were significant differences in the DAP values under the same mode among different programs (P<0.01). The DAP value was found significantly higher in the lumbar spine (P3) program than in other programs (P<0.01). There was no significant difference in the image qualities between pulsed fluoroscopy and high-contrast perspective modes, but the DAP values were increased significantly (P<0.01). There were significant differences in the image qualities under pulsed fluoroscopy mode between P2 and limbs (P4) programs.

    [Conclusion] Correct and reasonable use of the parameters of C-arm X-ray apparatus can effectively reduce radiation damage to medical professionals and patients.
