X射线仿真辐照材料是用于放射学和原子能利用等领域,代替人及生物体进行模拟实验的代用材料,其基本要求是材料与射线作用后对射线的衰减与所模拟的组织相近乃至相同.60年代以来,由于放射医学和原子能科学的广泛应用,该领域的研究受到越来越多的重视,成为生物医学工程中颇为活跃的一个方向.自从1906年使用第一种仿真材料至今,国际上已开发了上百种材料以适应多种要求.然而在材料设计方面,尽管人们先后提出了一些指导性方法,但由于这些方法在准确性、实用性
X-ray artificial radiation materials are substitute materials used in radiology and atomic energy fields to replace human beings and organisms to simulate experiments. The basic requirement is that the attenuation of rays after the action of materials and rays is similar to or even the same as that of the simulated tissues Since the 1960s, due to the extensive application of radiology and atomic energy science, more and more attention has been paid to this area of research, which has become a very active direction in biomedical engineering.Since the first artificial material was used in 1906, Hundreds of materials have been developed in the world to meet various requirements.However, in the aspect of material design, although some guiding methods have been proposed one after the other, due to their accuracy and practicability
