Abstract：
Interventional cardiology is characterized by high radiation exposure for both the patient and the operator. Adequate shielding and monitoring of the operator are fundamental to comply with radiation protection principles. In a previous work, the effect on the dose of the dosemeter position on the chest was studied. In this paper, the investigation has been completed, employing an anthropomorphic thorax phantom, equipped with arms. Although there are differences between the Monte Carlo simulations and the measurements, similar trends are observed, showing that the reduction in dose, due to the arms, is between 20 and 60%, compared with the situation without arms. For that reason, considering a dosemeter placed on the chest, the upper position, which is the least affected by the arms, should be preferred while the extreme lateral position, near the armpit, should be avoided.
摘要：
介入心脏病学的特点是对患者和操作者的高辐射暴露。对操作员进行充分的屏蔽和监测是符合辐射防护原则的基础。在以前的工作中，研究了剂量计位置对胸部剂量的影响。在本文中,调查已经完成,使用拟人化的胸部幻影，配备武器。尽管蒙特卡罗模拟和测量之间存在差异，观察到类似的趋势，表明剂量的减少，由于武器，在20%到60%之间，与没有武器的情况相比。出于这个原因,考虑到放在胸部的剂量计，上部位置，受武器影响最小，应该是首选，而极端的横向位置，在腋窝附近,应该避免。
