Abstract
This study aimed to evaluate radiation dose distribution to critical organs, specifically the lungs, heart, and breasts, during coronary angiography using the Alderson Rando phantom. Thermoluminescent dosimeters (TLDs) were positioned at different anatomical sites within the Alderson Rando ® phantom to measure radiation exposure in a controlled simulation replicating clinical coronary angiography conditions. Our findings indicated significant variability in lung doses, with the highest exposure observed in middle lung regions due to direct alignment with the primary X-ray beam path. Cardiac dose measurements showed a relatively uniform distribution, with elevated exposure in the basal and atrial regions, reflecting their proximity to the central beam. In the breast tissue, a pronounced dose asymmetry was noted, with the right breast, particularly lateral and posterior regions, receiving substantially higher radiation due to its closer positioning to the X-ray source and increased scatter. According to results, there are different levels of radiation exposure across organs and anatomical regions during coronary angiography. It can be concluded that implementing targeted dose-reduction strategies, such as shielding and optimized angulation, is essential to protect sensitive organs, with personalized imaging protocols recommended to enhance patient safety and minimize cumulative radiation risks.
期刊介绍:
Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
