红外热像仪对组织吸收微波及微波辐射器特性的研究

采用红外热像仪观察微波辐射器对组织的加温特性，并对微带辐射器和圆喇叭辐射器进行比较，结果表明，圆喇叭辐射器有一个加温区，而微带辐射器的辐射口面上有几个小加温区域，辐射器的放置位置与加温的分布有关，红外热像仪是评价辐射器性能，理解微波场在体内分布的良好工具。

Observation on property of microwave to tissues heating and microwave radiator with infrared thermography

in this paper, the property of microwave to tissues heating and microwave radiator was studied with infrared thermography,while the property of circular horn radiator and microstrip radiator to the tissues was also compared. The result showed that the tissues heated by circular horn radiator presented a larger heating area and those heated by microstrip radiator had several smaller heating areas. At the same time,the position of radiator was closely correlated with the temperature distribution. It is suggested that the infrared thermography is a good instrument for evaluating the microwave property and knowing the distribution of microwave radiation to the human tissues.
