The radiation burden of an individual patient caused by a radiological examination depends strongly on the technical parameters, such as kV and mAs. As an inquiry among 150 swiss physicians showed, rather different irradiation techniques are used for the same examination. Depending on these irradiation techniques, the doses may vary by almost a factor of ten. These large variations in dose indicate that in some clinics or hospitals the radiographic techniques and the film processing are at fault. This fact has to be accounted for by future efforts of quality assurance in diagnostic radiology.
放射检查给个体患者带来的辐射负担在很大程度上取决于技术参数，如千伏值（kV）和毫安秒（mAs）。一项对150名瑞士医生的调查显示，对于同一项检查，所采用的照射技术差异很大。根据这些照射技术的不同，剂量可能相差近十倍。剂量上的这些巨大差异表明，在一些诊所或医院，射线照相技术和胶片冲洗存在问题。诊断放射学未来的质量保证工作必须考虑到这一事实。
