Title:
磁性粒子による局部加熱の方法
Document Type and Number:
Japanese Patent JP4542897
Kind Code:
B2
Abstract:
The invention relates to a method as well as to a system for the local heating of a target region of an object by varying the magnetization of magnetic or magnetizable substances. A magnetic field is then generated whose magnetic field strength varies in space in such a manner that a first sub-region ( 301 ) of low magnetic field strength and a second sub-region ( 302 ) which encloses the first sub-region and has a higher magnetic field strength are formed in the target region. Subsequently, the position in space of the two sub-regions in the target region is varied with a given frequency for so long that the particles are heated to a desired temperature due to frequent variation of the magnetization.
