Description
、換算散乱係数
、及びプローブの先端での発光ファイバと集光ファイバとの中心間の間隔である。
は、ミー散乱の全散乱に対する換算散乱分率である。ミー散乱の換算散乱の傾きはbで示され、粒子の大きさと相関する。吸収体の均一な分布のために、全光吸収係数
は、吸収体の消衰係数と体積分率との積として算出される(図8参照)。
を、対象の4つの発色団のそれぞれの濃度によって加重される吸収係数の和としてモデル化する代わりに、組織吸収係数を、
として表すことが決定され、ここで
は、血液による吸収に相当し、
は、探査される体積内の水及び脂質による吸収を合わせたものに相当する。水及び脂質の体積分率は、νWL=[Lipid]+[H2O]である一方で、νBloodは、全血150mg/ml内のヘモグロビン濃度に対する血液の体積分率を示す。
として説明され、ここでRは、cmで表される平均血管半径である。血液に関する吸収係数は、
により与えられ、ここで
及び
は、それぞれ酸化ヘモグロビンHbO2及び還元ヘモグロビンHbの基本的な消衰係数スペクトルを示す。ヘモグロビンの全体量における酸化ヘモグロビン分率は、αBL=[HbO2]/([HbO2]+[Hb])と注記され、一般には血中酸素飽和度として知られている。測定される組織内の水及び脂質の存在による吸収は、
として規定される。
