摘要：
The aim of this study is to investigate the dose distribution in the process of X-ray imaging at Shanghai Synchrotron Radiation Facility. We used the Monte Carlo software EGSnrc based on the statistics of the beamline BL13W to simulate the actual irradiation environment and calculate the dose distribution. Three different sizes of sources and two different tomographic models were created to predict the dose distribution at different regions of interest (ROI) with different fields of view (FOV). The simulation results showed that the dose in ROI is higher. The dose accumulated in the ROI with smaller FOV was more concentrated and relatively smaller compared with the larger FOV. This calculated dose distribution provides guidance for in-vivo animal experiments and other applications such as microbeam therapy.
