| Abstract:: |
| Objective To provide suggestions for the optimization of radiation protection during interventional radiology procedures on the basis of investigate the quality control testing result of an interventional radiology equipment that has caused radiation skin damage. Method Five quality control testing reports on an interventional radiology device that has caused radiation skin injury to a patient in the past three years were selected to compare the differences between the testing results and analyze the existing problems. Results For the program of " Typical value of entrance surface air kerma in fluoroscopy mode", the testing result from the three institutions were in the range of 6.08-24.89 mGy/min, which met the requirements of relevant standards. The testing result of both the entrance surface air kerma and the ambient dose equivalent rate on the area of the operators differs greatly dependent on different exposure modes (normal fluoroscopic dose rates mode, high fluoroscopic dose rates mode, and cine mode) and different frame rates. The interventional operators for the device were lack of understanding of the influence on exposure modes, and patient doses were not recorded after an interventional surgery. Conclusions The patient dose can be significantly reduced by adjusting an interventional radiology equipment. It is recommended to increase the testing of reference point cumulative air kerma or dose-area product in future standard revisions and strengthen professional training for interventional operators and technicians, so that they can fully understand the differences in the effect of exposure mode of a interventional radiology equipment on patient and operator dose. |
