摘要: Heating pattern uniformity is provided in a coaxial microwave hyperthermia probe by varying the open area in the outer conductor in an axial direction such that there is a maximum open area in the axial center portion. The variations may be provided by winding an outer conductor in a helical pattern with a variable pitch or by cutting openings of axially varying size in a solid outer conductor. The invention is applicable to both flexible and rigid probes.
摘要翻译: 通过在轴向方向上改变外部导体中的开口面积,使得在轴向中心部分中存在最大开放面积,在同轴微波热疗探针中提供加热图案均匀性。 可以通过以固定的外部导体将具有可变节距的螺旋形外部导体卷绕成螺旋形图案或通过切割轴向变化的尺寸的开口来提供变化。 本发明适用于柔性和刚性探头。
