Abstract
【解決手段】 少なくとも1つの分割処理を用いて、関心のある所定の管状解剖学的構造体を分離し(210、220、230)、その関心構造体の少なくとも1つの属性を測定する。取得した画像データを用いて肺気道を測定するためのシステムは、画像データを取得するイメージング装置(110)と、該イメージング装置に連結された画像処理装置(120)とを含む。画像処理装置は、所定の関心気道を少なくとも1つの分割処理によって分離し、気道内の所定のポイントにおいて統計的手法を用いて、該所定の気道の内側境界に内側楕円をかつ該気道構造体の外側境界に外側楕円を適合させるように構成され、更に該内側及び外側楕円を用いて所定の気道の測定値を生成する。
