The present invention relates to accurate positioning for vessel intervention procedures, particularly to a method for accurate positioning for vessel intervention procedures, a medical imaging system for accurate positioning for vessel intervention procedures and a catheterization laboratory system for accurate positioning for vessel intervention procedures. First, at least one X-ray image of a vessel region of interest is acquired ( 24 ) with injected contrast agent. Further, vessel information data is identified ( 26 ) within the at least one acquired image. Then, first calcification features of the vessel in the vessel region of interest in the at least one acquired image are detected ( 28 ). Further, vessel representation is generated ( 30 ) using the vessel information data and the detected calcification features. Further, at least one current fluoroscopic image of the vessel region of interest is acquired ( 32 ). Then, second calcification features of the vessel in the vessel region of interest in the at least one current fluoroscopy image are detected ( 34 ), wherein the second calcification features are according to the first calcification features. Further, the vessel representation is registered ( 36 ) with the fluoroscopy image, wherein the calcification features are used for the registration. Then, a composite image is generated ( 38 ) by combining the vessel representation with the at least one fluoroscopy image. Further, a composite image is displayed ( 40 ). |
