Description
本願は、2017年10月13日に提出した第62/571,850(「‘850出願」)、代理事務所案件番号CCF―027057、名称が「神経血管束の超音波スペクトルパラメータ検出」の米国仮特許出願の優先権を主張し、当該‘850出願の内容全体は、参照により本明細書に組み込まれる。
ただし、fは周波数であり、T(f)及びR(f,d)は、超音波システムのトランスデューサ及びシステム電子機器のビームにより形成された送信伝達関数及び受信伝達関数を表し、D(f,d)は、回折効果を含み、A(f,d)は、重なる減衰を説明し、B(f)は、後方散乱伝達関数である。
(2)
ただし、S(f,d)は、頸動脈プラークからの測定信号であり、Sref(f,d)は、参照ファントムからの後方散乱の信号であり、また、
は、参照ファントム減衰と、トランスデューサと外膜との間の組織の上層の減衰との差を補償するための減衰係数である。このような補償減衰は、上記の減衰推定方法のうちの1つにより特定されるため、基本周波数及び高調周波数のそれぞれは、いずれも後方散乱伝達関数で表すことができる。
(3)
但し、pはAR次数として定義され、a[k]は、AR係数として評価され、e[n]は、ホワイトノイズランダムプロセスである。現在値は、過去の値の加重和としてモデル化され、ここで、加法性ノイズ項e[n]は、ホワイトノイズ分散σ2を有する。
パワースペクトル密度(PSD)は、ARモデルから推定することができ、以下の方程式に示す通りである。
(4)
但し、PSDは周波数(f)の関数としてのパワースペクトル密度であり、σ2は、ホワイトノイズの分散であり、a[k]は、AR係数であり、pは、モデルのAR次数である。Yule―Walker方程式系は、AR係数と、自己相関関数の間の関係を通じて取得され、この関係は、ARに基づくPSDを生成するために使用可能であり、次の形式となる。
(5)
但し、σ2はホワイトノイズの分散、RXXは、信号から計算された自己相関である。これらの方程式は、Levinson―Durbinアルゴリズムを使用して再帰的に解くことができ、ARパラメータ{a1、a2、・・・ 、ap、σ2}を増分的に計算する。ノイズの分散σ2は、このモデルのスペクトル推定のモデリング誤差に等しくなる。従って、誤差を申請者に関連するレベルを減少する(applicant dependent level)まで、ARパラメータを再帰的に計算し、次数pを大きくする。
(6)
(7)
(8)
但し、pは、AR次数であり、σ(p)2は、p次数の関数としての誤差であり、Nは、分析に使用されるサンプルの数である。
(9)
但し、S(f)は、ARモデルに基づく方法によって計算される正規化されたパワースペクトル密度(PSD)である。
(10)
ただし、空間周波数は、径方向座標角の定義を使用して効果的に置き換えられる。
(11)
及び
(12)
(13)
ただし、
