To provide configurations for arranging transducer arrays on a patient's head to apply tumor-treating fields (TTFields) into the brain at field strengths that are as uniform as possible throughout the entire brain.SOLUTION: In some embodiments, L-shaped sets of electrodes are positioned near the right and left ears, each with a horizontal arm above the ear and a vertical arm behind the ear. Optionally, these embodiments may be combined with a second pair of electrodes positioned on top of the head and behind the neck. In other embodiments, one pair of electrodes is positioned above the right ear and on the left rear portion of the neck; and a second pair of electrodes is positioned above the left ear and on the right rear portion of the neck. These configurations improve the uniformity of the applied electric fields throughout the entire brain, and are particularly useful for preventing and/or treating metastases.SELECTED DRAWING: Figure 4 【課題】本願は、脳全体にわたって可能な限り均一な電場強度で脳内に腫瘍治療電場（ＴＴ電場）を印加するように患者の頭部上にトランスデューサアレイを配置するための構成を開示する。【解決手段】一部実施形態では、Ｌ字型の電極組が左耳と右耳の近くに配置され、各電極組は耳の上方の水平アームと耳の後方の垂直アームを有する。任意選択的に、こうした実施形態は、頭頂部と後頚部に位置する第二対の電極と組み合わせられ得る。他の実施形態では、一対の電極が右耳の上方と左後頚部とに配置され、第二対の電極が左耳の上方と右後頚部に配置される。こうした構成は、脳全体にわたって印加される電場の均一性を改善し、特に転移を防止及び／又は治療するのに有用である。【選択図】図４
