Title:
多数の画像取得または再構築を使用する画像ベースのオブジェクトモデリングのためのシステム及び方法
Document Type and Number:
Japanese Patent JP6409073
Kind Code:
B2
Abstract:
Systems and methods are disclosed for modeling a patient's coronary vasculature, using a computer system. The method comprises determining one or more lumen diameters from one or more three-dimensional, computed tomography images of the coronary vasculature; determining one or more anatomical parameters of the vasculature from one or more intravascular ultrasound, angiography, or optical coherence tomography images obtained from within a lumen of the patient's coronary vasculature; extracting a geometric model of the vasculature from a reference image chosen from among the images and registering an object model to the geometric model based on the determined lumen diameters or anatomical parameters. The one or more lumen diameters are updated based on at least one of the determined anatomical parameters, using the registration of the object model to the geometric model; and a model of the patient's coronary vasculature is generated based on at least one updated lumen diameter.
