1. A method of generating an image of a coronary artery tree for a patient, the method comprising: acquiring data from the patient with an imaging device for a plurality of coronary artery segments of the coronary artery tree; and executing a set of code embodied in a storage medium with a processor, such that the executed code effectuates the following steps: generating a coronary artery tree image on a display including the plurality of coronary artery segments; accessing a plurality of known and pre-existing coronary artery tree patterns from a coronary artery tree pattern database; comparing the coronary artery tree image to the plurality of known and pre-existing coronary artery tree patterns; automatically selecting one of the plurality of known and pre-existing coronary artery tree patterns that most closely matches the coronary tree image, wherein this selected coronary artery tree pattern is a representative coronary artery tree pattern image for the patient; displaying the representative coronary artery tree pattern image on the display; and measuring a lesion in one of the plurality of coronary artery segments and automatically adding a lesion measurement to the representative coronary artery tree pattern image on the display.
