Abstract:
:The aim of the study was to estimate organ dose rate reduction to a female anthropomorphic phantom, which simulated the cardiologist, during percutaneous coronary interventions (PCI) when the patient's arm support was covered with 0.4-mm lead foil. Organ dose rates were determined using five radiation detectors inserted into the left eye, left thyroid, left breast, left liver lobe and uterus of the phantom. A male anthropomorphic phantom was placed on the examination table of an angiography system. Heart images of the patient phantom were acquired under 10 gantry angulations typical for PCI. The lead-covered arm support did not interfere with any of the cardiac images. The median organ dose rate reductions to the left eye, left thyroid, left breast, left liver lobe and uterus were 7.8, 36.0, 28.8, 35.7 and 33.5%, respectively. The lead-covered arm support substantially reduced scattered radiation to the female cardiologist without interfering with clinical environments.
