利用蒙特卡罗建模及估算儿童X-CT检查受照剂量

Abstract

Abstract: With the rapid development and wide application of X-ray CT examination, estimation of the dose from CT exposures has become a hot research spot, especially for children since they tend to have higher radiation sensitivity than adults. In this work, a CT scanner model was developed using the Monte Carlo technique and was applied to estimate organ doses derived from simulated CT exposures with a 1-year-old voxel phantom developed by our group. As a result, a database including doses to 36 organs and tissues was built for 1-year-old children. This medical exposuredose database provides a method for the estimation of 1-year-old patient doses in a variety of CT examinations. And it has been verified by measurement this method is convenient and reliable.

Key words: pediatric CT examination, CT scanner model, Monte Carlo, medical exposure, organ dose
