Abstract
Description
(体脂肪測定装置1Aの測定原理)
図1(A)および図1(B)を参照して、本実施の形態における体脂肪測定装置1A(図3参照)の測定原理について説明する。図1(A)は、胴部全体の生体インピーダンスを得る場合の電極配置を示した図である。図1(B)は、胴部のうちの背部側の表層部分の生体インピーダンスを得る場合の電極配置を示した図である。図1(A)および図1(B)においては、被験者をいずれも背中側から見た様子を示している。
胴部断面積Stは、胴部周囲長(いわゆるウエスト長)や、胴部の横幅および縦幅を用いて算出することが可能である。たとえば、胴部周囲長から胴部断面積Stを算出する場合には、胴部周囲長をtとすれば、胴部断面積Stは、以下の式(2)で近似できる。
上記式(2)で近似される胴部断面積Stは、誤差が多く含まれている可能性が高い。誤差を低減するための係数αをこれに乗ずることによって、より正確な胴部断面積Stを求めることが好ましい。係数αとしては、たとえば多数のX線CTによる画像サンプルに基づいて、当該画像サンプルから得られる胴部断面積St′と、上記tとの関係から、St′=α×t2/(4×π)を充足するαの最適値を求めることで得られる。
上記補正のために乗ずる係数αに関しては、被験者の性別、年齢、身長、体重等の情報(以下、これらを総称して被験者情報と称する)に応じて適宜最適化することが好ましい。当該被験者情報に応じて上記係数αの値を変更することにより、より高精度に胴部断面積Stが近似できることになる。
上記tは、上述のとおり胴部周囲長の値であり、胴部の大きさに関係する値である。この胴部の大きさに関係する値としては、上記tに限られず、たとえば胴部断面積Stを使用してもよいし、胴部の横幅または縦幅を使用してもよい。
上記tは、上述のとおり胴部周囲長の値であり、胴部の大きさに関係する値である。この胴部の大きさに関係する値としては、上記tに限られず、たとえば胴部断面積Stを使用してもよいし、胴部の横幅または縦幅を使用してもよい。
