基于CT值的组织辐射等效材料设计方法
Design Method Based on the CT Number for the Radiation Tissue-equivalent Materials/
摘要
Abstract
A design method based on the CT number for the radiation tissue-equivalent materials was brought up.According to the relationship between the CT number and the element content of radiation tissue-equivalent materials,a mathematic model was founded to calculate the mass ratio of the radiation tissue-equivalent materials under a determination energy of the rays(X or γ ray).The radiation tissue-equivalent materials with similar CT number of human body were designed.The mass attenuation coefficients of the radiation tissue-equivalent materials were compared to it of the body tissues.The results declared that this design method was feasible.The method provided in this paper processed some theoretical value to guide the design of the radiation tissue-equivalent materials under the energy used for medicine and the design of aerospace false.关键词
