This work aims to assess the efficacy of x-ray quality assurance tests undertaken on fluoroscopy units in the UK. Information was gathered on the results of image quality tests recommended by the reports of the Institute of Physics and Engineering in Medicine, and those additionally undertaken by medical physics departments. The assessment of efficacy considers the frequency with which a test result breaches the remedial level or other relevant threshold where applicable. The third quartile of those results exceeding the remedial level or threshold is used to estimate the severity of such a breach in terms of potential impact on patient dose and image quality. A risk assessment approach is then used to recommend to what degree, if any, the test should be included in an on-going test regimen.

Data was analysed from 469 testing sessions to 337 unique fluoroscopy units throughout the UK. Across all tests, the rate with which the remedial level was exceeded varied from 0–10.6%, with severity ranging from little or none to major degradation to image quality or significant increase on population dose. Where possible, the data has also been used to produce representative ranges for the results of image quality tests. These could be useful as an up to date comparator for those sites considering the purchase of or commissioning new equipment.

Overall the results indicate a wide range for the efficacy of those tests undertaken at present; this can be used to review local test protocols and to inform future changes to national guidance in the UK. The results also highlight some tests where measurement technique varies significantly throughout the UK, making any valid comparison difficult. This may indicate a need for further guidance on how best to undertake these tests.

这项工作旨在评估在英国的荧光检查设备上进行的X射线质量保证测试的功效。收集了有关医学物理与工程研究所的报告所推荐的图像质量测试结果的信息，以及医学物理部门另外进行的信息。功效评估考虑测试结果违反补救水平或其他适用阈值的频率。超过补救水平或阈值的那些结果的第三四分位数用于根据对患者剂量和图像质量的潜在影响来估计此类违规的严重性。然后，使用风险评估方法来建议应在何种程度上将该测试包括在正在进行的测试方案中。

在整个英国，从469个测试会话到337个独特的荧光检查单元对数据进行了分析。在所有测试中，补救水平的超出率在0-10.6％之间变化，严重程度从极少或根本没有到严重退化到图像质量或人口剂量显着增加。在可能的情况下，数据也已用于产生代表范围的图像质量测试结果。对于那些正在考虑购买或调试新设备的站点，这些可用作更新比较器。

总体而言，结果表明目前进行的那些测试的功效范围很广；这可用于审查本地测试协议，并为英国国家指南的未来更改提供信息。结果还突出显示了一些测试，这些测试的测量技术在整个英国范围内差异很大，因此很难进行有效的比较。这可能表明需要有关如何最好地进行这些测试的进一步指导。
