PROBLEM TO BE SOLVED: To provide microwave field-detecting needle assemblies, methods of manufacturing the same, methods of adjusting an ablation field radiating into tissue using the same, and systems including the same.SOLUTION: A microwave field-detecting needle assembly includes a needle assembly 110. The needle assembly includes a distal portion 130, a proximal portion 160, and a junction member 150 disposed between the distal portion and the proximal portion. The junction member includes a recess defined therein. The needle assembly also includes a rectifier element 58 disposed in the recess. The rectifier element includes a first terminal electrically coupled to the distal portion, and a second terminal electrically coupled to the proximal portion.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】マイクロ波場検出ニードルアセンブリ、その製造方法、それを用いた組織内照射焼灼領域の調節方法およびそれを含むシステムを提供する。【解決手段】マイクロ波場検出ニードルアセンブリはニードルアセンブリ110を含む。ニードルアセンブリは、遠位部分130と、近位部分160と、遠位部分と近位部分との間に配置された接合部材150とを含む。接合部材はその中に画定された凹部を含む。ニードルアセンブリは、凹部内に配置された整流素子58も含む。整流素子は、遠位部分に電気的に接続された第1の端子と、近位部分に電気的に接続された第2の端子とを含む。【選択図】図2
