METHOD FOR OFFERING VIRTUAL CONTRAST MEDIUM FOR BLOOD VESSEL IN LIVING BODY PART METHOD FOR OFFERING VIRTUAL CONTRAST MEDIUM FOR BLOOD VESSEL IN LIVING BODY PART AND METHOD FOR OFFERING VIRTUAL CONTRAST MEDIUM FOR BLOOD VESSEL IN LIVING BODY PART FOR ANGIOSCOPY

摘要

PROBLEM TO BE SOLVED: To reduce the quantity of contrast medium in intervention using a catheter in the artery of an arboroid system. SOLUTION: The method for offering a virtual contrast medium for a blood vessel in a living body part for an angioscope uses, for example, data derived from a 3D model using a magnetic resonance image forming computer tomography CT and a 3D angioscopy. This date is segmented for offering the segmented 3D modle of the blood vessel. A first procedure image is formed by injecting a contrast medium. Then, the 3D model is registered to the first procedure image, and 'a virtual camera parameter' is formed. The 3D model is rendered to be superimposed on an uncontrasting second procedure image to thereby attain vertual contrast.
