Abstract
Objectives: In this study, eye lens dose measurements were performed using two anthropomorphic phantoms simulating the cardiologist and patient during interventional procedures. Background: Interventional procedures known as areas with high potential risk and the cardiologists can receive relatively high doses to their eyes.
Methods: This study was comprised of both phantom and computer simulations. Thermoluminescent dosimeters (TLDs) and mEyeDose_X tool were used to measure and calculate eye lens doses for the cardiologist. 144 TLDs measurements were performed using cardiac protocol for three angiographic projections: anterior-posterior (AP), left anterior oblique 90 degrees (LAO90) and left anterior oblique 45 degrees with cranial 30 degrees (spider) angulations. All cine and fluoroscopy modes including the projections used in this study performed with and without protection tools.
Results: The annual equivalent doses with protective tools using mEyeDose_X were found to be 1.831 and 1.424 mSv/year, whereas the values using phantom were found to be 2.204 and 1.802mSv/year for the lens of lift and right eye respectively.
Conclusion: The annual doses reported in this study are almost comparable to other studies performed on interventional cardiology (IC) procedures. The highest dose rate in the lens was 20.21 +/- 0.015 mSv/h without protective tools in cine mode for spider projection. Cardiologists may therefore easily exceed the lens dose limit if protective tools are not used. (c) 2019 Elsevier Inc. All rights reserved.
