Popis: | This work aims to assess the efficacy of current x-ray quality assurance (QA) testing regimes on tube and generator systems for general radiographic usage in the UK. 1393 sets of QA results data from nine UK medical physics departments were collected and analysed. Test failure rates ranged from 0% to 39% and were used to assess the likelihood of the test finding a fault. The magnitude of the recorded faults were used to assess the severity of the failure with due consideration to its impact on image quality and patient dose. The severity and likelihood of the faults were used along with a risk matrix to assess the efficacy of each test. Eleven tests were graded 'orange' (indicating an effective test that should be continued), four tests were graded 'yellow' (indicating a less effective test that may be continued with a lower frequency considered) and four tests were graded green (indicating a low efficacy test that could be removed from test regimes). |
