PROBLEM TO BE SOLVED: To provide a method of adjusting an ablation field radiating into tissue by which ultrasound image representative of a tissue region is acquired during energy delivery into the tissue region.SOLUTION: The method of adjusting an ablation field radiating into tissue includes the initial step of providing a handheld device including a phased antenna array and an ultrasound transducer array (910). The method includes the steps of positioning a tissue-contact surface of the handheld device adjacent to tissue (920), activating the phased antenna array to deliver energy through the tissue-contact surface to generate an ablation field in targeted tissue, activating the ultrasound transducer array to acquire ultrasound image data representative of the targeted tissue during energy delivery into the targeted tissue by the phased antenna array (930), and selectively steering the focal point of energy delivery in tissue to adjust the ablation field radiating into tissue (940).COPYRIGHT: (C)2012,JPO&INPIT【課題】組織領域内にエネルギーを伝達する間にその組織領域を視覚化することができる組織内照射焼灼領域の調整方法を提供する。【解決手段】組織内照射焼灼領域の調整方法は、位相アンテナアレイおよび超音波トランスデューサアレイを含む手持ち式装置を用意する最初の工程を含む(910)。手持ち式装置の組織接触面を組織に隣接して配置する工程(920)と、位相アンテナアレイを作動させて、組織接触面を通してエネルギーを伝達して標的組織内に焼灼領域を生成する工程と、位相アンテナアレイによって標的組織内にエネルギーを伝達する間に、超音波トランスデューサアレイを作動させて、標的組織を表す超音波画像データを取得する工程(930)と、組織内のエネルギー伝達焦点を選択的に誘導して組織内照射焼灼領域を調整する工程(940)とを含む。【選択図】図9
