Microwave hyperthermia probe.

摘要

Heating pattern uniformity is provided in a coaxial microwave hyperthermia probe (10) by varying the open area in the outer conductor (13) 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 (17) in a helical pattern with a variable pitch or by cutting openings (34) of axially varying size in a solid outer conductor (33). The invention is applicable to both flexible and rigid probes.
