Abstract
Description
LR=L/LT
他の式を使用してもよい。一実施形態では、1組の計算された経路、例えば、内腔における計算された全経路長さ、及び指定のポイント又はターゲット(1つ又は複数)への計算された長さを決定することができる。既知の又は推定された全内腔長さを決定することもでき、そしてその既知の又は推定された長さと、計算された全長さとの間の比を決定することができる。この比は、指定のポイント(1つ又は複数)への装置の計算された経路長さに適用して、そのポイント(1つ又は複数)へのより正確な推定経路長さ又は距離を決定することができる。
LR=L/LT L≦LT/2
LR=(LT−L)/LT L>LT/2
LA=7*L/LT L≦LT/2
LA=7*(LT−L)/LT L>LT/2
他の式を使用してもよい。
以上、幾つかの実施形態について本発明を詳細に説明したが、本発明の多数の変更、修正及び他の応用がなされ得ることが明らかであろう。本発明の実施形態は、ここに述べたオペレーションを遂行するための他の装置を含んでもよい。このような装置は、ここに述べた要素を一体化してもよいし、又は同じ目的を果たすための別の要素を備えてもよい。当業者であれば、本発明の真の精神に包含されるこのような全ての修正や変更は、特許請求の範囲に網羅されることが明らかであろう。
