Description
Ah≡{k|k∈A1かつ max(A3)より大きな任意のl∈A2についてk<l} (6)
として定義される。ここで、max(A3)はA3の最大の要素であり、A3が空であれば−∞として定義される。下記は等価な定義である:
Ah≡{k|k∈A1かつ任意のl∈A2'についてk<l} (7)
ここで、
A2'≡{l|l∈A2かつ任意のj∈A3についてl>j} (8)
心臓と肺の間の境界は、Ahの最大の要素に基づいて推定される。たとえば、A1={5,6,…,50}、A2={3,4,49,50,51}およびA3={11,12,13}であれば、A2'={49,50,51}であり、Ah={5,6,…,48}であり、推定される境界角
rc(n,θ)≡wdrd,l(n,θ)+wsrs,h(n,θ) ステップS650
であり、hl(n)は0.8MHzでカットオフする101タップの実低域通過フィルタであり、hh(n)は1.15MHzでカットオフする101タップの実高域通過フィルタである。肺組織からのエコーはrd,l(n,θ)を優遇し(低周波数成分によく応答するので)、心臓組織からのエコーはrs,h(n,θ)を優遇する(より多くの動きのため)。wdおよびwsは、二つの力をバランスさせるために使われる重みである。rc(n,θ)後の信号処理は図4Cにおけるrs(n,θ)後の処理と同じままである。例示的なパラメータはwd=1.2、ws=1、fu1=1.4MHz、fl=1.2MHzおよびfu2=1.5MHzである。閾値fu1、flおよびfu2のうちの一つまたは複数および対応してA1、A2およびA3のうちの一つまたは複数を使うことが本発明の意図される範囲内である。
