8. A method of segmenting tissue of an organ, said method comprising:
- accessing image data from an imaging modality acquisition system wherein the image data comprises at least one of a three dimensional single or multiple cardiac phase dataset and/or a three dimensional multi-temporal phase dataset of a feature of interest in an organ or tissue, wherein the data is acquired in conjunction with or without at least one of an imaging agent, blood, a contrast agent, and a biomedical agent, wherein the data can be acquired in a state of cardiac stress or in non-cardiac stress state;
wherein segmentation is performed on the data by using a method which includes histogram analysis by classification of elements of vascular tissue as one of epicardial fat, calcium, lumen/contrast, and fatty plaque/thrombus of the data into different densities through the use of a line fitting technique on the histogram, where each element defines the outer wall of the vessel. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
