| Abstract:: |
| Objective To investigate radiation dose to the patients undergoing interventional radiology and make radiation risk assessment. Methods Data was collected on 198 instances of 10 interventional radiology procedures by using Philips Allura Xper FD20 DSA, which was equipped with the transparent ionization chamber system in compliance with IEC 60601-2.Patient peak skin dose and effective dose were estimated. Results Cumulative fluoroscopy time was 2.1-80.9 min, and number of images was 15-678 frames, and DAP was 11-825 Gy·cm2, and CD was 24-3374 mGy. A total of 16 cases monitored for PSD were above 1 Gy and 79 cases monitored for E were above 20 mSv. Conclusions Substantial number of cases exceeded the dose threshold for erythema. Due attention should be paid to radiation protection of patients. |
