چکیده مقاله:
Introduction: The study focused on the assessment of quality control tests in X-ray units from the Southern regions of Tanzania to yield the data required to create and implement quality control policies and strategies.Material and Methods: Quality control tests were conducted on twenty-six diagnostic X-ray units in private and government hospitals in southern regions of Tanzania during ۲۰۲۰ – ۲۰۲۱. The tests focused on the reproducibility of accelerating tube potential, time reproducibility, the accuracy of accelerating tube potential, half-value layer, beam alignment, and collimation. The statistical analyses were done by using the Microsoft Excel spreadsheet of ۲۰۱۳. The results were compared with the tolerance limits. Results: Of all X-ray units evaluated, ۹۲.۳۱% had kVp accuracy within the tolerance limit of ۵% and ۹۲% of the X-ray units had acceptable HVL values ≥ ۲.۳ mm Al at ۸۰ kVp. Moreover, results have shown that ۸۶.۹۶% and ۸۲.۶۱% of X-ray units had acceptable beam collimation (≤ ±۲ cm) and beam alignment (≤۳% of the X-ray source and X-ray table), respectively.Conclusion: Comprehensive regulatory inspections and equipment maintenance plans in the Southern zone is significantly required due to the high patient workload which attributes frequent breakdown of X-ray units. Moreover, radiographers need to be trained on how to minimize and detect beam misalignment and collimation failure since the most unacceptable results were observed from these tests.
