Analysis of 2D/3D image data for 3D visualization during image-guided interventions

Some methods of 2D/3D image data quantification and generation for 3D visualization during image-guided interventions, which are believed to enable a new understanding of the patient and the treatment, are discussed. X-ray projection imaging of the blood vessels has been the primary method for assessing the extent of arterial narrowing. A new vessel-sizing technique can determine the centerline, and extract gray-scale intensity-data profiles perpendicular to the centerline along lines perpendicular to the vessel axis. Vessel tortuousity can be measured by using the data in the images themselves for calibration of the imaging geometry, optimizing the consistency of the calculated 3D with the data in the images. Computational fluid dynamics (CFD) calculations can provide the basis for new insight into flow patterns and treatment paths that would lead to the optimal treatment of aneurysm.
