| 目的 通过能响比较,评估8种剂量仪器能否满足临床乳腺摄影剂量测量的要求。 方法 遵从GB/T 19629-2005标准,用一参考级剂量器具,采用SSDL已建成的在25～40 kV的10种标准辐射质,分别对8种乳腺摄影剂量仪器进行能量响应测定。结果 除2000S能响较差外,其他剂量仪器的能量响应因子变化范围都在±5%内一致。结论 电离室型剂量仪器能响特性要好于其他类型剂量仪器。 |

| Objective To evaluate whether eight kinds of dosimeters satisfy the clinical mammography dose measurement through the comparison of energy response.Methods According to GB/T 19629-2005,the energy responses of eight available mammography dosimeters were determined for ten standard radiation qualities in the range 25-40 kVp at the SSDL using a refrence-class dosimeter.Results Except 2000S, the energy response factors of all the other dosimeters were consistent within ±5%.Conclusions The energy response of ionizing chamber type is better than other types of dosimeters. |
