Zusammenfassung:PROBLEM TO BE SOLVED: To provide an external magnetic field generator for a rotary electron spin resonance/nuclear magnetic resonance imaging apparatus capable of enlarging a diameter of a magnet for a high magnetic field irrelevant to a radius of a measurement part.SOLUTION: The external magnetic field generator for a rotary electron spin resonance/nuclear magnetic resonance imaging apparatus includes: a first board 1 that includes a weak-magnetic-force magnet 3 for electron spin resonance and a strong-magnetic-force magnet 4 for nuclear magnetic resonance, disposed on board surfaces 1a and 1b; a second board 2 that includes a weak-magnetic-force magnet 3 for electron spin resonance and a strong-magnetic-force magnet 4 for nuclear magnetic resonance that are disposed corresponding to the first board 1, and that is disposed parallel to the first board 1 at an interval apart; and means for synchronously rotating the first board 1 and the second board 2.SELECTED DRAWING: Figure 2 【課題】測定部位の半径とは無関係に高磁場用の磁石の直径を拡大することが可能な回転型電子スピン共鳴/核磁気共鳴画像装置用外部磁場発生装置を提供すること。【解決手段】盤面1a,1bに配置された電子スピン共鳴用弱磁力磁石3と核磁気共鳴用強磁力磁石4とを備えた第1の基盤1、第1の基盤1に対応するように配置された電子スピン共鳴用弱磁力磁石3と核磁気共鳴用強磁力磁石4とを備え、第1の基盤1に対して平行に間隔を開けて配置された第2の基盤2、及び第1の基盤1及び第2の基盤2を同期回転させる手段を備える電子スピン共鳴/核磁気共鳴画像装置用外部磁場発生装置。【選択図】図2
