P.G.Seiler等「原体照射方法における腫瘍位置の連続精密測定のための新しいトラッキング方法」、Phys.Med.Biol.45(2000)N103-N110 Wynn等「進歩した超伝導傾斜計/磁力計アレイおよび新しい信号処理方法」IEEE Trans.Magn.11 701-7 本発明の目的の一つは、センサーの定位とトラッキングの精度と解像度を高くすることである。
Claims (5)
- 複数のコイルを有する磁場ジェネレータにより生成された磁場内のキャプチャ範囲中のセンサーをトラッキングするトラッキングシステムであって、
前記磁場ジェネレータの前記複数のコイルは、前記複数のコイルの相互の位置及び/または方向を調節することにより前記複数のコイルがそれぞれ発生させるビームの方向と位置を調節することにより、前記キャプチャ範囲のサイズ及びオリエンテーションのうち少なくとも一方を調節するように、前記センサーに対して可動であり、前記センサーは前記キャプチャ範囲内にあるトラッキングシステム。 - 前記磁場ジェネレータの前記複数のコイルを、前記キャプチャ範囲のサイズを小さくするように動かす、請求項1に記載のトラッキングシステム。
- 前記複数のコイルは前記キャプチャ範囲を狭めるために、前記磁場ジェネレータを移動させることにより移動可能である、請求項1に記載のトラッキングシステム。
- 前記磁場ジェネレータの前記複数のコイルを、関心領域が前記キャプチャ範囲の中心になるように動かす、請求項1に記載のトラッキングシステム。
- コンピュータ化されたトラッキングシステムに、磁場ジェネレータの複数のコイルにより生成された磁場に対応するキャプチャ範囲中のセンサーをトラッキングさせるコンピュータプログラムであって、
(a)前記キャプチャ範囲を画定するために、前記磁場ジェネレータの前記複数のコイルにより磁場を生成するステップと、
(b)前記キャプチャ範囲内の前記センサーを含む関心領域を特定するステップと、
(c)前記複数のコイルの相互の位置及び/または方向を調節することにより前記複数のコイルがそれぞれ発生させるビームの方向と位置を調節することにより、前記磁場を前記関心領域に狭めることにより前記キャプチャ範囲を狭めるステップであって、前記磁場ジェネレータの前記複数のコイルを、アクチュエータにより、前記関心領域に対して動かすステップと、
(d)ステップ(a)から(c)を繰り返すステップと、
を実行させるコンピュータプログラム。
