    • Embodiments of the present invention are generally related to apparatus and methodology of thermal applicators in cancer therapy. In particular, the present embodiments are directed to a technique called “nanoparticle ferromagnetic resonance heating,” where ferromagnetic resonance heating in addition to an RF hyperthermia treatment is used to cause cell apoptosis and necrosis. An apparatus for carrying out a ferromagnetic resonance heating treatment of a tumor, comprises a volume concentration of super paramagnetic particles contained within the interior of the tumor, the concentration ranging from about 0.1 to about 1 percent; a magnetic field source configured to deliver a gradient DC magnetic field to the region of the tumor; and an energy source configured to deliver to the tumor an RF field at a frequency ranging from about 100 to 200 MHz. The apparatus of claim 1, wherein the super paramagnetic particles are selected from the group consisting of maghemite (γ-Fe2O3) based compounds, and yttrium iron garnet (Y3Fe5O12) based compounds.
    • 本发明的实施例通常涉及癌症治疗中的热敷装置的装置和方法。 特别地,本实施例涉及一种称为“纳米颗粒铁磁共振加热”的技术,其中使用除RF热疗处理之外的铁磁共振加热以引起细胞凋亡和坏死。 用于进行肿瘤的铁磁共振加热处理的装置包括包含在肿瘤内部的超顺磁性颗粒的体积浓度,其浓度范围为约0.1%至约1%; 磁场源,被配置为向所述肿瘤的区域递送梯度DC磁场; 以及能量源,其被配置为以大约100至200MHz的频率向所述肿瘤递送RF场。 2.根据权利要求1所述的设备,其中所述超顺磁性颗粒选自由以下物质组成的组:基于磁赤铁矿(γ-Fe 2 O 3 O 3)的化合物和钇铁石榴石(Y 3 5 12 12)基的化合物。
