| 中文摘要: |
| 目的 建立电磁波照射时大鼠的电磁模型,并计算大鼠体内的比吸收率(specificabsorptionrate,SAR)分布。方法 在用计算机辅助设计(CAD)软件建立大鼠三维模型而获得的电磁模型的基础上,采用时域有限差分法计算某一电磁波照射条件下大鼠体内SAR。结果 利用建立的大鼠电磁模型计算了电磁波照射时体内的平均SAR和SAR分布。结论 所建立的大鼠电磁模型可以用于电磁波照射时SAR的计算,为相关的电磁生物效应研究提供一个参数。 |

| Objective To establish a numerical rat model and calculate the SAR distribution in a rat exposed to electromagnetic wave irradiation. Methods Based on a 3D rat model established by using CAD software,a numerical rat was calculated adopting FDTD method to get SAR distribution(average SAR and distributed SAR) under a certain condition of electromagnetic wave irradiation.Results Both average SAR and distributed SAR were worked out by the numerical rat model exposed to electromagnetic wave irradiation.Conclusion The numerical rat model can be used for calculating the SAR distribution in rats exposed to electromagnetic wave irradiation,and provides a reference for related electromagnetic-biological effects. |
