Abstract

The temperature pattern produced in phantoms containing simulated bone and muscle components was determined for 434-MHz electromagnetic radiation. A parallelepiped phantom was employed in this study and heating was conducted for 15 minutes using a commercially available diathermy unit. Both slab and cylindrical bone geometries were investigated, as well as the influence of depth in muscle of the bone component on the resulting temperature pattern. The temperature perturbation produced by bone irradiated by 434-MHz radiation was found to vary drastically with the bone geometry, as well as with the depth of the bone in muscle.

摘要

针对434兆赫电磁辐射，测定了含有模拟骨骼和肌肉成分的体模中产生的温度模式。本研究采用了平行六面体体模，并使用市售透热疗法设备进行了15分钟的加热。研究了平板和圆柱形骨骼几何形状，以及骨骼成分在肌肉中的深度对所得温度模式的影响。发现434兆赫辐射照射骨骼所产生的温度扰动会随骨骼几何形状以及骨骼在肌肉中的深度而急剧变化。
