| Abstract:: |
| Objective To establish a method for reducing the dose to the eye lens of interventional staff,and provide the data basis for improving radiological protection measures. Methods One piece of interventional equipment coupled with conventional auxiliary protective devices and two types of common neural interventional procedures were selected to monitor 46 and 35 procedures before and after the device modification.The doses to the eye lens of staff were measured with direct-reading dosimeters for analysis of dose trends. Results After modification of the devices,the average dose to the left eye lens decreased from (9.71±10.86) to (3.23±5.59)μSv for the first operator,from (9.51±12.34) to (0.68±0.78)μSv for the second in cerebral angiography;whereas the dose decreased from (14.83±19.13) to (4.17±4.59) for the first operator and from (14.12±21.76) to (1.23±1.57)μSv for the second in embolization procedure,respectively.The left eye lens doses measured before and after the modification showed significant difference (U=-2.760,-2.467,-1.967,-2.655,P<0.05). Conclusions The modification of the auxiliary radiological protective devices may effectively reduce the dose to the eye lens dose.This method was shown to be feasible for the improvement of radiological protection of interventional staff. |
