摘要
放射诊断成像的频次和对公众的累积剂量不断提升,带来的辐射风险引起广泛关注,但人体所接受辐射剂量的准确测量很难实现.蒙特卡罗模拟作为以概率统计理论为指导的数值计算方法,已应用于各种放射诊断成像的剂量评估、成像优化和辐射防护.本文就蒙特卡罗方法的原理、蒙特卡罗模拟的建模过程及其在放射诊断剂量估算的应用进展进行综述.
Abstract
The increasing frequency of radiographic diagnostic imaging and the cumulative dose to the public from radiation has raised widespread concerns.However,accurate measurement of the radiation dose received by the human body is difficult to achieve.Monte Carlo simulation,as a numerical computational method guided by probability statistics theory,has been applied to various dose assessments,imaging optimizations,and radiation protection in radiographic diagnostic imaging.We provide a comprehensive review of the principles of the Monte Carlo method,the modelling process of Monte Carlo simulation and the progress of its application to diagnostic radiological dose estimation.
