Patent ID: 7993274

Claim:
A method of cardiac diagnostics, the method comprising: obtaining in a processor coronary tree segmentation from intravascular ultrasound (IVUS) views to obtain cardiac volume information; splitting in a processor the volume into portions to obtain an adjacency graph for display on a graphical user interface; computing in a processor a mean of a sub-volume of the volume to obtain a mean threshold above which indicates that calcifications are present; obtaining in a processor gray value segmentation of the sub-volume, the gray value segmentations each having a value related to the mean of the sub-volume, including the threshold above which indicates that the calcifications are present; defining in a processor a centerline of a blood vessel that avoids calcifications within the blood vessel; and detecting in a processor an actual centerline of the blood vessel and enhancing lumen visualization of the blood vessel for display on the graphical user interface.
