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.
