MEDICAL IMAGE VIEWING DEVICE FOR NAVIGATION IN X RAY IMAGING MEDICAL IMAGING SYSTEM AND METHOD FOR PROVIDING IMPROVED X RAY IMAGE NAVIGATION INFORMATION

摘要

A medical image viewing device (14) for navigation in X ray imaging is proposed which inter alia comprises a processing unit (30). The processing unit (30) is configured to perform a 3D 2D registration of a preoperative three dimensional volume based on geometry parameters of an image data providing unit which provides fluoroscopy images of an object of interest and a plurality of structures with interfering motions to be removed for creating digitally reconstructed radiograph images of these structures for each fluoroscopyimage. These are subtracted from the respective fluoroscopy images to generate structure suppressed fluoroscopy images free from interfering motions. Based on these an angiographic image sequence is generated performing a motion estimation of the structures.
