Introduction: Regular quality control of radiology devices and fixing their defects can play a crucial role in reducing absorbed dose of patients, increasing their longevity, and improving the quality of radiographic images. This study was aimed at performing quality control according to the standards and features of radiology machines in the teaching hospitals of Hormozgan Province. Methods: Several parameters were examined in this study, including voltage accuracy, voltage reproducibility, exposure time reproducibility, output linearity with mA, and adaptation of optical field with radiation field. Results: Evaluation of voltage accuracy showed that the radiology devices of No. 3 in Shahid Mohammadi Hospital of Bandar Abbas, No. 1 in Hazrat Abolfazl Hospital of Minab, and No. 1 in Hazrat Fatemeh Zahra Hospital of Qeshm exceeded the normal ranges in all voltages, and the radiology devices of Shariati Hospital in Bandar Abbas in 78 kV and 85 kV. Conclusion: Quality control of radiology devices in health centers reduces patients’ absorbed dose during various radiographies, increases their efficiency and longevity, and improves the quality of radiographic images and the disease diagnosis by physician.
