Performance Assessment and Measurements of Mammographic Glandular Dose Using 8000 NERO-mAx and Radcal Acuu-pro X-ray Test Devices

Abstract

Article InfoIn the present study, a non invasive X-ray test device (8000 Victoreen NERO mAx), and radiation monitor controller (RADCAL-9010) system used to measure the Breast Entrance Dose (BED) in mammographic projection at King Abdulazaiz University Hospital (KAUH), Saudi Arabia. The age distribution and the compressed breast thickness (CBT) of the patients determined based on the information survey from the radiology department logbook. The Average Glandular Dose (AGD) calculated based on the value of the entrance dose and some other imaging technique factors. The X-ray quality control tests were evaluated for beam quality assessment, tube potential accuracy, time accuracy, and reproducibility according to the American College of Radiology (ACR) protocol for the quality control of the mammography imaging technique (Code of practice-TRS 457). The results showed that, good correlation was found between the results obtained from the above mentioned dosemetric systems. The calculated AGD found lower than the international recommended value (3.0 mGy). Also the results give acceptable levels for patient absorbed dose and safety.
