Claim Text:
1. A computer-implemented method of modeling at least a portion of a patient's vasculature, using a computer system, the method comprising: determining one or more lumen diameters of the patient's coronary vasculature from one or more three-dimensional, computed tomography images of the patient's coronary vasculature; determining one or more anatomical parameters of the patient's coronary vasculature from one or more intravascular ultrasound (“IVUS”), angiography or optical coherence tomography (“OCT”) images of the patient's coronary vasculature obtained from within a lumen of the patient's coronary vasculature; extracting a geometric model of the patient's coronary vasculature from one or more of the three-dimensional, computed tomography images or IVUS, angiography, or OCT images designated as a reference image; registering an object model to the geometric model based on the one or more determined lumen diameters or one or more determined anatomical parameters; using the registration of the object model to the geometric model to update the one or more lumen diameters derived from three three-dimensional, computed tomography images based on at least one of the one or more determined anatomical parameters derived from the IVUS, angiography, or OCT images; and generating a model of the patient's coronary vasculature based on at least one of the one or more updated lumen diameters.
