| 摘 要： | 目的：通过提高辐射器的性能进而增加肿瘤热疗的适应范围和疗效。方法：在ＭａｘＳＡＲ（最大比吸收率）处增加垫片测量ＥＨＳ，不同介质作藕合剂测量ＥＨＤ。结果：增加垫片可不同程度增加ＥＳＨ，最好的提高了４２．９％，水作介质最好，ＥＨＤ约为 ３ ｃｍ。结论：通过降低热点区 ＳＡＲ值的方法增加 ＥＨＳ，用表面冷却法增加 ＥＨＤ，提高微波辐射器性能。

| Abstract: | Objective: To make Hyperthermia more effective in the treament of tumor by improving the capabilities of mi-crowave applicator. Methods: Comparing the EHS values at the location of Max SAR between adding or not adding a cushionthere. Measuring EHD in different kinds of medium as bolus. Results: EHS were enlarged in some degree by adding a cushionat the location of Max SAR, the best is 42.9 %. Water was the most effective medium as bolus, its EHD was 3 cm approximate-ly. Conclusion: With the enlarged EHS by decrease the SAR at hot spot and increased EHD by means of water superficialcooling, the MW-applicator capabilities can be improved. |
