| 中文摘要: |
| 用水、明胶、油及n-丙醇等材料制成的一种超声体模,具有与人体软组织相似的超声特性,包括声速、密度、衰减系数和散射。并利用本所新研制的多元阵列超声治癌热疗系统对体模的温升性能进行了测试,其结果与活体动物组织的实验结果相接近,同时发现血液灌流在生物热传导中作用不可忽视。 |
| 英文摘要: |
| A kind of tissue phantom made from water,gelatin,oil and n-propanol was developed.The ultrasonic parameters of this kind of phantom,including speed of sound,attenuation coefficient, density and backscatter level are similar to human soft tissue.With the Ultrasound Hyper-thermia System that was newly manufactured by our institute The temperature elevation of the phantom was measured.The result was consistent with the temperature rising curves that are obtained from the vitro animals,but the effect of the blood perfusion can not be ignored. |
